VLA Resolves Unexpected Radio Structures in the Perseus Cluster of Galaxies [PDF]
Astrophysical Journal, 2021 We present new deep, high-resolution, 1.5 GHz observations of the prototypical nearby Perseus galaxy cluster from the Karl G. Jansky Very Large Array. We isolate for the first time the complete tail of radio emission of the bent-jet radio galaxy NGC 1272,

Exploring the AGN–Ram Pressure Stripping Connection in Local Clusters [PDF]
Astrophysical Journal, 2021 Ram pressure stripping (RPS) by the intracluster medium is one of the most advocated mechanisms that affect the properties of cluster galaxies. A recent study based on a small sample has found that many galaxies showing strong signatures of RPS also ...

THE STRUCTURE OF NUCLEAR STAR CLUSTERS IN NEARBY LATE-TYPE SPIRAL GALAXIES FROM HUBBLE SPACE TELESCOPE WIDE FIELD CAMERA 3 IMAGING [PDF]
Astronomical Journal, 2015 We obtained Hubble Space Telescope/Wide Field Camera 3 imaging of a sample of ten of the nearest and brightest nuclear clusters (NCs) residing in late-type spiral galaxies, in seven bands that span the near-UV to the near-IR. Structural properties of the

OmegaWINGS: spectroscopy in the outskirts of local clusters of galaxies [PDF]
, 2017 Studies of the properties of low-redshift cluster galaxies suffer, in general, from small spatial coverage of the cluster area. WINGS, the most homogeneous and complete study of galaxies in dense environments to date, obtained spectroscopic redshifts for

The Hierarchical Distribution of the Young Stellar Clusters in Six Local Star-forming Galaxies [PDF]
, 2017 We present a study of the hierarchical clustering of the young stellar clusters in six local (3–15 Mpc) star-forming galaxies using Hubble Space Telescope broadband WFC3/UVIS UV and optical images from the Treasury Program LEGUS (Legacy ExtraGalactic UV ...

A General Precipitation-limited LX–T–R Relation among Early-type Galaxies [PDF]
, 2017 The relation between X-ray luminosity (LX) and ambient gas temperature (T) among massive galactic systems is an important cornerstone of both observational cosmology and galaxy-evolution modeling.

Gravitational redshift of galaxies in clusters from the sloan digital sky survey and the Baryon Oscillation spectroscopic survey. [PDF]
Physical Review Letters, 2014 The gravitational redshift effect allows one to directly probe the gravitational potential in clusters of galaxies. Following up on Wojtak et al. [Nature (London) 477, 567 (2011)], we present a new measurement.

The formation of isolated ultradiffuse galaxies in romulus25
, 2021 We use the Romulus25 cosmological simulation volume to identify the largest-ever simulated sample of field ultra-diffuse galaxies (UDGs). At z=0, we find that isolated UDGs have average star formation rates, colors, and virial masses for their stellar ...

Observational Tests of Nonlocal Gravity: Galaxy Rotation Curves and Clusters of Galaxies [PDF]
, 2014 aspect of gravity in this theory can simulate dark matter; indeed, in the Newtonian regime of nonlocal gravity, we recover the phenomenological Tohline-Kuhn approach to modified gravity.

Redshift Evolution of Green Valley Galaxies in Different Environments from the Hyper Suprime-Cam Survey [PDF]
Astrophysical Journal, 2020 Green valley galaxies represent the population that is likely to transition from star-forming to quiescent phases. To investigate the role of the environment in quenching star formation, we use the wide-field data from the Hyper Suprime-Cam Strategic ...
