Hot Atmospheres, Cold Gas, AGN Feedback and the Evolution of Early Type Galaxies: a Topical Perspective
N. Werner, B. R. McNamara, E. Churazov +1
Most galaxies comparable to or larger than the mass of the Milky Way host hot, X-ray emitting atmospheres, and many such galaxies are radio sources. Hot atmospheres and radio jets…
Search for HI emission from superdisk candidates associated with radio galaxies
Abhijeet Anand, Nirupam Roy, Gopal-Krishna
Giant gaseous layers (termed "superdisk") have been hypothesized in the past to account for the strip-like radio emission gap (or straight-edged central brightness depression) obse…

Timescales for Hi consumption and SFR depletion of satellite galaxies in groups
Mika Rafieferantsoa, Romeel Davé, Thorsten Naab
We investigate the connection between the HI~content, SFR and environment of galaxies using a hydrodynamic simulation that incorporates scaling relations for galactic wind and a he…
The impact of AGN on stellar kinematics and orbits in simulated massive galaxies
Matteo Frigo, Thorsten Naab, Michaela Hirschmann +5
We present a series of 20 cosmological zoom simulations of the formation of massive galaxies with and without a model for AGN feedback. Differences in stellar population and kinema…
Jellyfish galaxies with the IllustrisTNG simulations: I. Gas-stripping phenomena in the full cosmological context
Kiyun Yun, Annalisa Pillepich, Elad Zinger +8
We use IllustrisTNG, a suite of gravity and MHD simulations, to study the demographics and properties of jellyfish galaxies in the full cosmological context. By jellyfish galaxies,…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
Synthetic nebular emission from massive galaxies II: ultraviolet-line diagnostics of dominant ionizing sources
Michaela Hirschmann, Stéphane Charlot, Anna Feltre +3
We compute synthetic optical and ultraviolet (UV) emission-line properties of galaxies in a full cosmological framework by coupling, in post-processing, new-generation nebular-emis…
Inner bars also buckle. The MUSE TIMER view of the double-barred galaxy NGC 1291
J. Mendez-Abreu, A. de Lorenzo-Caceres, D. A. Gadotti +8
Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin and evolution is still…
Resolving on 100 pc scales the UV-continuum in Lyman- emitters between redshift 2 to 3 with gravitational lensing
E. Ritondale, M. W. Auger, S. Vegetti +1
We present a study of seventeen LAEs at redshift 23 gravitationally lensed by massive early-type galaxies (ETGs) at a mean redshift of approximately 0.5. Using a fully Bayesia…
Zooming in on accretion - II. Cold Circumgalactic Gas Simulated with a super-Lagrangian Refinement Scheme
