Galaxy growth in the concordance $\Lambda$CDM cosmology
, 2007 We use galaxy and dark halo data from the public database for the Millennium Simulation to study the growth of galaxies in the De Lucia et al. (2006) model for galaxy formation.

Quasars Can Signpost Supermassive Black Hole Binaries
The Astrophysical JournalSupermassive black holes (SMBHs) are found in the centers of massive galaxies, and galaxy mergers should eventually lead to SMBH mergers. Quasar activity has long been associated with galaxy mergers, so here we investigate if supermassive black hole ...

FAST MOLECULAR OUTFLOWS IN LUMINOUS GALAXY MERGERS: EVIDENCE FOR QUASAR FEEDBACK FROM HERSCHEL [PDF]
, 2013 We report the results from a systematic search for molecular (OH 119 μm) outflows with Herschel/PACS in a sample of 43 nearby (z < 0.3) galaxy mergers, mostly ultraluminous infrared galaxies (ULIRGs) and QSOs. We find that the character of the OH feature

Mergers and galaxy evolution [PDF]
, 2007 Galaxy merging is the late time manifestation of the galaxy formation process and likely significantly effects z < 1 galaxies. A "maximum reasonable rate" model for merging finds a ,~ 2 mag K band increase in the luminosities of dwarf galaxies so that they contribute significantly to the faint counts, with spirals and ellipticals being far less ...

Forming Young Bulges within Existing Disks: Statistical Evidence for External Drivers
, 2003 Contrary to traditional models of galaxy formation, recent observations suggest that some bulges form within preexisting disk galaxies. Such late-epoch bulge formation within disks seems to be linked to disk gas inflow and central star formation, caused ...

ChemPlusChem, EarlyView.The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

On the Use of Galaxy Catalogs in Gravitational-wave Parameter Estimation
The Astrophysical JournalA major challenge in gravitational-wave (GW) multimessenger astrophysics is the imprecise localization of GW compact binary mergers. We investigate the use of a method to include galaxy catalog information in performing parameter estimation of these ...

The History of Galaxy Mergers in IllustrisTNG
UniverseThe process of galaxy evolution over cosmic time is not yet fully understood, since there is a debate on the impact of galaxy collisions on the star formation and metallicity.

The role of mergers and halo spin in shaping galaxy morphology [PDF]
, 2016 Mergers and the spin of the dark matter halo are factors traditionally believed to determine the morphology of galaxies within a $\Lambda$CDM cosmology.
