Decoupling the rotation of stars and gas -- II: the link between black hole activity and MaNGA kinematics in TNG
Christopher Duckworth, Tjitske K. Starkenburg, Shy Genel +4
We study the relationship between supermassive black hole (BH) feedback, BH luminosity and the kinematics of stars and gas for galaxies in IllustrisTNG. We use a sample of galaxies…
The impact of quenching on galaxy profiles in the Simba simulation
Sarah Appleby, Romeel Davé, Katarina Kraljic +2
We study specific star formation rate (sSFR) and gas profiles of star forming and green valley galaxies in the Simba cosmological hydrodynamic simulation. Star-forming galaxy half-…
Decoupling the rotation of stars and gas -- I: the relationship with morphology and halo spin
Christopher Duckworth, Rita Tojeiro, Katarina Kraljic
We use a combination of data from the MaNGA survey and MaNGA-like observations in IllustrisTNG100 to determine the prevalence of misalignment between the rotational axes of stars a…
The impact of the connectivity of the cosmic web on the physical properties of galaxies at its nodes
Katarina Kraljic, Christophe Pichon, Sandrine Codis +11
We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We co…
Multi-tracer extension of the halo model: probing quenching and conformity in eBOSS
Shadab Alam, John A. Peacock, Katarina Kraljic +2
We develop a new Multi-Tracer Halo Occupation Distribution (\texttt{MTHOD}) framework for the galaxy distribution and apply it to the extended Baryon Oscillation Spectroscopic Surv…
Time-slicing spiral galaxies with SDSS-IV MaNGA
Thomas Peterken, Amelia Fraser-McKelvie, Alfonso Aragón-Salamanca +6
Spectra of galaxies contain a wealth of information about the stellar populations from which they are made. With integral-field unit (IFU) surveys, such data can be used to map out…
And yet it flips: connecting galactic spin and the cosmic web
Katarina Kraljic, Romeel Dave, Christophe Pichon
We study the spin alignment of galaxies and halos with respect to filaments and walls of the cosmic web, identified with DisPerSE, using the SIMBA simulation from z=0-2. Massive ha…
Group connectivity in COSMOS: a tracer of mass assembly history
E. Darragh-Ford, C. Laigle, G. Gozaliasl +11
Cosmic filaments are the channel through which galaxy groups assemble their mass. Cosmic connectivity, namely the number of filaments connected to a given group, is therefore expec…
A diversity of starburst-triggering mechanisms in interacting galaxies and their signatures in CO emission
Florent Renaud, Frederic Bournaud, Oscar Agertz +5
The physical origin of enhanced star formation activity in interacting galaxies remains an open question. Knowing whether starbursts are triggered by an increase of the quantity of…
Alignment between filaments and galaxy spins from the MaNGA integral-field survey
Alex Krolewski, Shirley Ho, Yen-Chi Chen +4
Halos and galaxies acquire their angular momentum during the collapse of surrounding large-scale structure. This process imprints alignments between galaxy spins and nearby filamen…
