Image

Meenakshi, Moun,   Mukherjee, Dipanjan,   Wagner, Alexander Y.,   Nesvadba, Nicole P.~H.,   Morganti, Raffaella,   Janssen, Reinier M.~J.

We use the results of relativistic hydrodynamic simulations of jet- interstellar medium (ISM) interactions in a galaxy with a radio- loud AGN to quantify the extent of ionization in the central few kpcs of the gaseous galactic disc. We perform post-process radiative transfer of AGN radiation through the simulated gaseous...

Far and extreme UV radiation feedback in molecular clouds and its influence on the mass and size of star clusters

Image

Fukushima, Hajime,   Yajima, Hidenobu

We study the formation of star clusters in molecular clouds by performing three-dimensional radiation hydrodynamics simulations with far ultraviolet (FUV; 6 eV≦hν≦13.6 eV) and extreme ultraviolet (EUV; hν≧13.6 eV) radiative feedback. We find that the FUV feedback significantly suppresses the star formation in diffuse clouds with the initial surface densities...

Image

Tokuda, Kazuki,   Kondo, Hiroshi,   Ohno, Takahiro,   Konishi, Ayu,   Sano, Hidetoshi,   Tsuge, Kisetsu

We have analyzed the data from a large-scale CO survey toward the northern region of the Small Magellanic Cloud (SMC) obtained with the Atacama Compact Array (ACA) stand-alone mode of ALMA. The primary aim of this study is to comprehensively understand the behavior of CO as an H2 tracer in...

Tracing the Ionization Structure of the Shocked Filaments of NGC 6240

Image

Medling, Anne M.,   Kewley, Lisa J.,   Calzetti, Daniela,   Privon, George C.,   Larson, Kirsten,   Rich, Jeffrey A.

We study the ionization and excitation structure of the interstellar medium in the late-stage gas-rich galaxy merger NGC 6240 using a suite of emission-line maps at ~25 pc resolution from the Hubble Space Telescope, Keck/NIRC2 with Adaptive Optics, and the Atacama Large Millimeter/submillimeter Array (ALMA). NGC 6240 hosts a superwind...

Impact of relativistic jets on the star formation rate: a turbulence-regulated framework

Image

Mandal, Ankush,   Mukherjee, Dipanjan,   Federrath, Christoph,   Nesvadba, Nicole P.~H.,   Bicknell, Geoffrey V.,   Wagner, Alexander Y.

We apply a turbulence-regulated model of star formation to calculate the star formation rate (SFR) of dense star-forming clouds in simulations of jet-interstellar medium (ISM) interactions. The method isolates individual clumps and accounts for the impact of virial parameter and Mach number of the clumps on the star formation activity....

Tracing the Milky Way's Vestigial Nuclear Jet

Image

Cecil, Gerald,   Wagner, Alexander Y.,   Bland-Hawthorn, Joss,   Bicknell, Geoffrey V.,   Mukherjee, Dipanjan

MeerKAT radio continuum and XMM-Newton X-ray images have recently revealed a spectacular bipolar channel at the Galactic Center that spans several degrees (~0.5 kpc). An intermittent jet likely formed this channel and is consistent with earlier evidence of a sustained, Seyfert-level outburst fueled by black hole accretion onto Sgr A*...

Formation of the first galaxies in the aftermath of the first supernovae

Image

Abe, Makito,   Yajima, Hidenobu,   Khochfar, Sadegh,   Dalla Vecchia, Claudio,   Omukai, Kazuyuki

We perform high-resolution cosmological hydrodynamic simulations to study the formation of the first galaxies that reach the masses of 108-9 h-1 M⊙ at z = 9. The resolution of the simulations is high enough to resolve minihaloes and allow us to successfully pursue the formation of multiple Population (Pop) III...

Internal R-process Abundance Spread of M15 and a Single Stellar Population Model

Image

Tarumi, Yuta,   Yoshida, Naoki,   Inoue, Shigeki

The member stars in globular cluster M15 show a substantial spread in the abundances of r-process elements. We argue that a rare and prolific r-process event enriched the natal cloud of M15 in an inhomogeneous manner. To critically examine the possibility, we perform cosmological galaxy formation simulations and study the...

Resolved simulations of jet-ISM interaction: Implications for gas dynamics and star formation

Image

Mukherjee, Dipanjan,   Bicknell, Geoffrey V.,   Wagner, Alexander Y.

Relativistic jets can interact with the ambient gas distribution of the host galaxy, before breaking out to larger scales. In the past decade, several studies have simulated jet-driven outflows to understand how they affect the nearby environment, and over what spatial and temporal scales such interactions occur. The simulations are...

Fragmentation of ring galaxies and transformation to clumpy galaxies

Image

Inoue, Shigeki,   Yoshida, Naoki,   Hernquist, Lars

We study the fragmentation of collisional ring galaxies (CRGs) using a linear perturbation analysis that computes the physical conditions of gravitational instability, as determined by the balance of self-gravity of the ring against pressure and Coriolis forces. We adopt our formalism to simulations of CRGs and show that the analysis...

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). IV. Rapidly Growing (Super)Massive Black Holes in Extremely Radio-loud Galaxies

Image

Ichikawa, Kohei,   Yamashita, Takuji,   Toba, Yoshiki,   Nagao, Tohru,   Inayoshi, Kohei,   Charisi, Maria

We present the optical and infrared properties of 39 extremely radio- loud galaxies discovered by cross-matching the Subaru/Hyper Suprime-Cam (HSC) deep optical imaging survey and VLA/FIRST 1.4 GHz radio survey. The recent Subaru/HSC strategic survey revealed optically faint radio galaxies (RG) down to gAB ~26, opening a new parameter space...

Radiation hydrodynamics simulations of line-driven AGN disc winds: metallicity dependence and black hole growth

Image

Nomura, Mariko,   Omukai, Kazuyuki,   Ohsuga, Ken

Growth of the black holes (BHs) from the seeds to supermassive BHs (SMBHs, ~109M⊙) is not understood, but the mass accretion must have played an important role. We performed 2D radiation hydrodynamics simulations of line-driven disc winds considering the metallicity dependence in a wide range of the BH mass, and...

Jet-driven AGN feedback on molecular gas and low star-formation efficiency in a massive local spiral galaxy with a bright X-ray halo

Image

Nesvadba, N.~P.~H.,   Wagner, A.~Y.,   Mukherjee, D.,   Mandal, A.,   Janssen, R.~M.~J.,   Zovaro, H.

It has long been suspected that powerful radio sources may lower the efficiency with which stars form from the molecular gas in their host galaxy, however so far, alternative mechanisms, in particular related to the stellar mass distribution in the massive bulges of their host galaxies, have not been ruled...

Radiation hydrodynamics simulations of massive star cluster formation in giant molecular clouds

Image

Fukushima, Hajime,   Yajima, Hidenobu

By performing 3D radiation hydrodynamics simulations, we study the formation of young massive star clusters (YMCs; M* > 104 M⊙) in clouds with the surface density ranging from Σcl = 80 to 3200 M⊙ pc-2. We find that photoionization feedback suppresses star formation significantly in clouds with low-surface density. Once...

Shock-multicloud interactions in galactic outflows - II. Radiative fractal clouds and cold gas thermodynamics

Image

Banda-Barragán, W.~E.,   Brüggen, M.,   Heesen, V.,   Scannapieco, E.,   Cottle, J.,   Federrath, C.

Galactic winds are crucial to the cosmic cycle of matter, transporting material out of the dense regions of galaxies. Observations show the coexistence of different temperature phases in such winds, which is not easy to explain. We present a set of 3D shock- multicloud simulations that account for radiative heating...

Instability analysis for spiral arms of local galaxies: M51, NGC 3627, and NGC 628

Image

Inoue, Shigeki,   Takagi, Toshinobu,   Miyazaki, Atsushi,   Cooper, Erin Mentuch,   Egusa, Fumi,   Yajima, Hidenobu

We investigate dynamical states of grand-design spiral arms in three local galaxies: M51, NGC 3627, and NGC 628. Based on linear perturbation analysis considering multiple components in the galaxies, we compute instability parameters of the spiral arms using their observational data and argue whether the arms will fragment by their...

Polarization images of accretion flow around supermassive black holes: Imprints of toroidal field structure

Image

Tsunetoe, Yuh,   Mineshige, Shin,   Ohsuga, Ken,   Kawashima, Tomohisa,   Akiyama, Kazunori

With unprecedented angular resolution, the Event Horizon Telescope (EHT) has opened a new era of black hole studies. We have previously calculated the expected polarization images of M 87* with EHT observations in mind. There, we demonstrated that circular polarization (CP) images, as well as linear polarization (LP) maps, can...

s-process enrichment of ultrafaint dwarf galaxies

Image

Tarumi, Yuta,   Suda, Takuma,   van de Voort, Freeke,   Inoue, Shigeki,   Yoshida, Naoki,   Frebel, Anna

We study the production of barium (Ba) and strontium (Sr) in ultrafaint dwarf (UFDs) galaxies. Both r- and s- processes produce these elements, and one can infer the contribution of the r-process from the characteristic r-process abundance pattern, whereas the s-process contribution remains largely unknown. We show that the current...

UV line-driven disc wind as the origin of UltraFast Outflows in AGN

Image

Mizumoto, Misaki,   Nomura, Mariko,   Done, Chris,   Ohsuga, Ken,   Odaka, Hirokazu

UltraFast Outflows (UFOs) are observed in some active galactic nuclei (AGN), with blueshifted and highly ionized Fe-K absorption features. AGN typically have an ultraviolet (UV-) bright accretion flow, so UV line driving is an obvious candidate for launching these winds. However this mechanism requires material with UV opacity, in apparent...

Effects of the Compressibility of Turbulence on the Dust Coagulation Process in Protoplanetary Disks

Image

Sakurai, Yoshiki,   Ishihara, Takashi,   Furuya, Hitomi,   Umemura, Masayuki,   Shiraishi, Kenji

Planetesimals are believed to be formed by the coagulation of dust grains in the protoplanetary disk turbulence. However, the bouncing and fragmentation barriers have not been completely solved, particularly for silicate dust. To circumvent these barriers, the turbulent clustering of dust particles must be properly treated. According to the minimum-mass...
