GASP XVIII: Star formation quenching due to AGN feedback in the central region of a jellyfish galaxy [PDF]

, 2019
We report evidence for star formation quenching in the central 8.6 kpc region of the jellyfish galaxy JO201 which hosts an active galactic nucleus, while undergoing strong ram pressure stripping.

Galaxy formation in the Planck cosmology – I. Matching the observed evolution of star formation rates, colours and stellar masses [PDF]

, 2014
We have updated the Munich galaxy formation model to the Planck first-year cosmology, while modifying the treatment of baryonic processes to reproduce recent data on the abundance and passive fractions of galaxies from z = 3 down to z = 0. Matching these

Disk Galaxy Formation in a LambdaCDM Universe

, 2004
We describe hydrodynamical simulations of galaxy formation in a Lambda cold dark matter (CDM) cosmology performed using a subresolution model for star formation and feedback in a multiphase interstellar medium (ISM).

Galaxy morphology and star formation in the Illustris Simulation at z = 0 [PDF]

, 2015
We study how optical galaxy morphology depends on mass and star formation rate (SFR) in the Illustris Simulation. To do so, we measure automated galaxy structures in 10 808 simulated galaxies at z = 0 with stellar masses 10^(9.7) < M_*/M_⊙ < 10^(12.3 ...

Suppression of Star Formation in Galaxy Pairs

The Astrophysical Journal
We investigate the suppression of star formation in galaxy pairs based on the isolated galaxy pair sample derived from the Sloan Digital Sky Survey survey.

CEERS Key Paper. V. Galaxies at 4 < z < 9 Are Bluer than They Appear–Characterizing Galaxy Stellar Populations from Rest-frame ∼1 μm Imaging

The Astrophysical Journal Letters, 2023
We present results from the Cosmic Evolution Early Release Survey on the stellar population parameters for 28 galaxies with redshifts 4 < z < 9 using imaging data from the James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) combined with ...

Quasar induced galaxy formation: a new paradigm ? [PDF]

, 2009
We discuss observational evidence that quasars play a key role in the formation of galaxies starting from the detailed study of the quasar HE0450-2958 and extending the discussion to a series of converging evidence that radio jets may trigger galaxy ...

Formation Models of Galaxies [PDF]

Astrophysics and Space Science, 1995
Unfortunately Dr. White was not able to finish a written version of his presentation at the Symposium in time for inclusion in these proceedings. He refers the interested readers to his lecture notes at the August 1993 Les Houches summer school (White, 1995).

Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at z ≥ 10?

The Astrophysical Journal Letters, 2023
Recent photometric detections of extreme ( z > 10) redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation and in the most acute case, in tension with ΛCDM itself.
