Ionized gas kinematics of massive elliptical galaxies in CALIFA and in cosmological zoom-in simulations
Jan Florian, Bodo Ziegler, Michaela Hirschmann +5
(Abridged) We present an investigation of kinematical imprints of AGN feedback on the Warm Ionized gas Medium (WIM) of massive early-type galaxies (ETGs). To this end, we take a tw…

We study the evolutionary trend of the total density profile of early-type galaxies (ETGs) in IllustrisTNG. To this end, we trace ETGs from to and measure the power-law…
The REQUIEM Survey I: A Search for Extended Ly-Alpha Nebular Emission Around 31 z>5.7 Quasars
Emanuele Paolo Farina, Fabrizio Arrigoni-Battaia, Tiago Costa +19
The discovery of quasars few hundred megayears after the Big Bang represents a major challenge to our understanding of black holes and galaxy formation and evolution. Their luminos…
Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). IV. Lensed quasar search in the HSC survey
James H. H. Chan, Sherry H. Suyu, Alessandro Sonnenfeld +9
Strong gravitationally lensed quasars provide powerful means to study galaxy evolution and cosmology. We use Chitah to hunt for new lens systems in the Hyper SuprimeCam Subaru S…
Structural and photometric properties of barred galaxies from the Auriga cosmological simulations
Guillermo Blázquez-Calero, Estrella Florido, Isabel Pérez +6
In this work we analyse the structural and photometric properties of 21 barred simulated galaxies from the Auriga Project. These consist of Milky Way-mass magneto-hydrodynamical si…
Braginskii viscosity on an unstructured, moving mesh accelerated with super-time-stepping
Thomas Berlok, Ruediger Pakmor, Christoph Pfrommer
We present a method for efficiently modelling Braginskii viscosity on an unstructured, moving mesh. Braginskii viscosity, i.e., anisotropic transport of momentum with respect to th…
X-ray Signatures of Black Hole Feedback: Hot Galactic Atmospheres in IllustrisTNG and X-ray Observations
Nhut Truong, Annalisa Pillepich, Norbert Werner +6
Hot gaseous atmospheres that permeate galaxies and extend far beyond their stellar distribution, where they are commonly referred to as the circumgalactic medium (CGM), imprint imp…
Magnetising the circumgalactic medium of disk galaxies
Ruediger Pakmor, Freeke van de Voort, Rebekka Bieri +7
The circumgalactic medium (CGM) is one of the frontiers of galaxy formation and intimately connected to the galaxy via accretion of gas on to the galaxy and gaseous outflows from t…
Chemodynamics of barred galaxies in cosmological simulations: On the Milky Way's quiescent merger history and in-situ bulge
F. Fragkoudi, R. J. J. Grand, R. Pakmor +9
We explore the chemodynamical properties of a sample of barred galaxies in the Auriga magneto-hydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) bulges,…
The GRIFFIN project -- Formation of star clusters with individual massive stars in a simulated dwarf galaxy starburst
Natalia Lahén, Thorsten Naab, Peter H. Johansson +5
We describe a population of young star clusters (SCs) formed in a hydrodynamical simulation of a gas-rich dwarf galaxy merger resolved with individual massive stars at sub-parsec s…
The Milky Way total mass profile as inferred from Gaia DR2
Marius Cautun, Alejandro Benitez-Llambay, Alis J. Deason +7
We determine the Milky Way (MW) mass profile inferred from fitting physically motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various hydrodynamical…
Systematic errors in strong gravitational lensing reconstructions, a numerical simulation perspective
W. Enzi, S. Vegetti, G. Despali +2
We present the analysis of a sample of twenty-four SLACS-like galaxy-galaxy strong gravitational lens systems with a background source and deflectors from the Illustris-1 simulatio…
The effects of cosmic rays on the formation of Milky Way-mass galaxies in a cosmological context
Tobias Buck, Christoph Pfrommer, Rüdiger Pakmor +2
We investigate the impact of cosmic rays (CR) and different modes of CR transport on the properties of Milky Way-mass galaxies in cosmological magneto-hydrodynamical simulations in…
Simulating the interstellar medium of galaxies with radiative transfer, non-equilibrium thermochemistry, and dust
Rahul Kannan, Federico Marinacci, Mark Vogelsberger +4
We present a novel framework to self-consistently model the effects of radiation fields, dust physics and molecular chemistry (H) in the interstellar medium (ISM) of galaxies.…
Empirical constraints on the formation of early-type galaxies
Benjamin P. Moster, Thorsten Naab, Simon D. M. White
We present constraints on the formation and evolution of early-type galaxies (ETGs) with the empirical model EMERGE. The parameters of this model are adjusted so that it reproduces…
