Segregation properties of galaxies

The Astrophysical Journal, 1990
Using the recently completed Southern Sky Redshift Survey, in conjunction with measurements of the central surface brightness, the existence of segregation in the way galaxies of different morphology and surface brightness are distributed in space is investigated.

Using large galaxy surveys to distinguish z~0.5 quiescent galaxy models [PDF]

, 2014
One of the most striking properties of galaxies is the bimodality in their star-formation rates. A major puzzle is why any given galaxy is star-forming or quiescent, and a wide range of physical mechanisms have been proposed as solutions. We consider how

Modeling the dispersion measure—redshift relation for fast radio bursts

Frontiers in Astronomy and Space Sciences
This theoretical work investigates different models to predict the redshift of fast radio bursts (FRBs) from their observed dispersion measure (DM) and other reported properties.

The host galaxies of Compact Steep Spectrum and Gigahertz-Peaked Spectrum radio sources

, 2008
I will review some of the developments in studies of the host galaxy properties of Compact Steep Spectrum (CSS) and GigaHertz-Peaked Spectrum (GPS) radio sources.

The dependence of galaxy assembly bias on the selection criteria, number density, and redshift of galaxy samples

Astronomy & Astrophysics
One of the key factors influencing galaxy clustering in the nonlinear regime is galaxy assembly bias, which describes the dependence of galaxy clustering on halo properties beyond halo mass.

The Vimos VLT Deep Survey: Stellar mass segregation and large-scale galaxy environment in the redshift range 0.2 [PDF]

, 2009
Hierarchical models of galaxy formation predict that the properties of a dark matter halo depend on the large-scale environment surrounding the halo. As a result of this correlation, we expect massive haloes to be present in larger number in overdense ...

Interpreting galaxy properties with improved modelling [PDF]

Proceedings of the International Astronomical Union, 2019
AbstractObservations of star-forming galaxies in the distant Universe have confirmed the importance of massive stars in shaping galaxy emission and evolution. Distant stellar populations are unresolved, and the limited data available must be interpreted in the context of stellar population models.

Shining Light on Merging Galaxies I: The Ongoing Merger of a Quasar with a `Green Valley' Galaxy

, 2011
Serendipitous observations of a pair z = 0.37 interacting galaxies (one hosting a quasar) show a massive gaseous bridge of material connecting the two objects.

Galaxy-galaxy weak-lensing measurement from SDSS: II. host halo properties of galaxy groups [PDF]

, 2017
As the second paper of a series on studying galaxy-galaxy lensing signals using the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our measurement and modelling of the lensing signals around groups of galaxies.
