An analysis of the evolving comoving number density of galaxies in hydrodynamical simulations [PDF]
, 2015 The cumulative comoving number-density of galaxies as a function of stellar mass or central velocity dispersion is commonly used to link galaxy populations across different epochs.

Non-parametric analysis of the rest-frame UV sizes and morphological
disturbance amongst L* galaxies at 4
, 2016 We present the results of a study investigating the sizes and morphologies of redshift 4 < z < 8 galaxies in the CANDELS GOODS-S, HUDF and HUDF parallel fields.

Chemie Ingenieur Technik, EarlyView., 2023 Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Secular Evolution of Galaxy Morphologies [PDF]
, 1996 Today we have numerous evidences that spirals evolve dynamically through various secular or episodic processes, such as bar formation and destruction, bulge growth and mergers, sometimes over much shorter periods than the standard galaxy age of 10-15 Gyr.

The Thick Disk in the Galaxy NGC 4244 from S^4G Imaging [PDF]
, 2010 If thick disks are ubiquitous and a natural product of disk galaxy formation and/or evolution processes, all undisturbed galaxies that have evolved during a significant fraction of a Hubble time should have a thick disk. The late-type spiral galaxy NGC

Tidal Tails and Galaxy Evolution [PDF]
, 2000 We review recent results on the tidal structures of spiral galaxies. Topics included are general characteristics of tails; kinematics of tidal structures and dark haloes of host galaxies; frequency of tidal distortions at z~1.Comment: 5 pages ...

Galaxy-galaxy(-galaxy) lensing as a sensitive probe of galaxy evolution
, 2012 The gravitational lensing effect provides various ways to study the mass environment of galaxies. We investigate how galaxy-galaxy(-galaxy) lensing can be used to test models of galaxy formation and evolution.

Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups
The Astrophysical Journal, 2023 We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching in 0.2 < z < 0.8 groups.

The Evolution of Galaxy Groups and of Galaxies Therein [PDF]
, 2007 Properties of groups of galaxies depend sensitively on the algorithm for group selection, and even the most recent catalogs of groups built from redshift-space selection should suffer from projections and infalling galaxies. The cosmo-dynamical evolution of groups from initial Hubble expansion to collapse and virialization leads to a fundamental track (
