Galaxy Evolution in Compact Groups. III. Structural Analysis of Galaxies and Dynamical State of Non-isolated Compact Groups

The Astrophysical Journal
Compact groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset—non-isolated CGs—are embedded within major structures. Using multiband S-PLUS data, we analyse galaxies in 122 non-isolated

Discovery of a transparent sightline at {\rho} < 20 kpc from an interacting pair of galaxies

, 2013
We report the discovery of a transparent sightline at projected distances of {\rho} < 20 kpc to an interacting pair of mature galaxies at z = 0.12. The sightline of the UV-bright quasar PG1522+101 at z = 1.328 passes at {\rho} = 11.5 kpc from the higher ...

Quantified HI Morphology I: Multi-Wavelengths Analysis of the THINGS Galaxies [PDF]

, 2011
Galaxy evolution is driven to a large extent by interactions and mergers with other galaxies and the gas in galaxies is extremely sensitive to the interactions. One method to measure such interactions uses the quantified morphology of galaxy images. Well-

Galaxies Caught in Transition: The Role of Group Environment in Shaping the Mass–Size Relation in the Local Universe

The Astrophysical Journal
The stellar mass–size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs), low-mass groups ( M _vir ≤ 10 ^13 M _⊙ ), and high-mass groups, comparing

Collisional interaction limits between dark matters and baryons in `cooling flow' clusters

, 2007
Presuming weak collisional interactions to exchange the kinetic energy between dark matter and baryonic matter in a galaxy cluster, we re-examine the effectiveness of this process in several `cooling flow' galaxy clusters using available X-ray ...

Large Scale Structure in Dark Matter and Galaxies [PDF]

, 2009
Galaxy evolution and AGN growth in the early universe are believed to be strongly driven by merging (hierarchical growth) and galaxy dynamical interactions.

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.

Merging Gas-rich Galaxies That Harbor Low-luminosity Twin Quasars at z = 6.05: A Promising Progenitor of the Most Luminous Quasars

The Astrophysical Journal
We present Atacama Large Millimeter/submillimeter Array [C ii ] 158 μ m line and underlying far-IR continuum emission observations (0.″57 × 0.″46 resolution) toward a quasar–quasar pair system recently discovered at z = 6.05. The quasar nuclei (C1 and C2)
