The Evolution of Galaxy Groups and of Galaxies Therein [PDF]
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 (

Galaxy Group Ellipticity Confirms a Younger Cosmos
We present an analysis of the ellipticities of galaxy groups, derived from the spatial distribution of member galaxies, revealing a notable incongruity between the observed local galaxy groups and their counterparts in the Lambda cold dark matter ...

A Nearby Isolated Dwarf: Star Formation and Structure of ESO 006–001
Observations with the Hubble Space Telescope unexpectedly revealed that the dwarf galaxy ESO 006–001 is a near neighbor to the Local Group at a distance of 2.70 ± 0.11 Mpc.

The Photography of Groups of Galaxies [PDF]
The method of combining several negatives together is at last coming into use. Forty years ago this method was used for the first time by Leontovsky in Leningrad. Putting together many negatives he was able to do photometry of M31 to fainter magnitudes than was possible photoelectrically.

TRIM24 and TRIM28 are androgen receptor (AR) coregulators which exhibit increased expression with cancer progression. Both TRIM24 and TRIM28 combine to influence the response of castrate‐resistant prostate cancer (CRPC) cells to AR inhibitors by mediating AR signalling, regulation of MYC and upregulating VEGF to promote angiogenesis. Castrate‐resistant

Detection of a Spatially Extended Stellar Population in M33: A Shallow Stellar Halo?
We analyze the outer regions of M33, beyond 15 kpc in projected distance from its center, using Subaru/Hyper Suprime-Cam multicolor imaging. We identify red giant branch (RGB) stars and red clump (RC) stars using the surface-gravity-sensitive NB515 ...
