The Manhattan Suite: Accelerated Galaxy Evolution in the Early Universe

The Astrophysical Journal
Observational advances have allowed the detection of galaxies, protoclusters, and galaxy clusters at higher and higher redshifts, opening a new view into extreme galaxy evolution.

Major Mergers Mean Major Offset: Drivers of Intrinsic Scatter in the MGCS–Mh Scaling Relation for Massive Elliptical Galaxies

The Astrophysical Journal
In this work, we determine the total globular cluster (GC) counts and globular cluster system (GCS) total mass estimates for 27 extremely massive elliptical galaxies.

The Relationships between Active Galactic Nucleus Power and Molecular Gas Mass within 500 pc of the Center of Elliptical Galaxies

The Astrophysical Journal
The physical quantity that directly controls the feedback of active galactic nuclei (AGNs) in elliptical galaxies remains to be determined. The discovery of molecular gas around the AGNs suggests that the gas is fueling the AGNs.

Spectroscopic and X-ray Modeling of the Strong Lensing Galaxy Cluster MACS J0138.0-2155

The Open Journal of Astrophysics
We model the total mass and galactic substructure in the strong lensing galaxy cluster MACS J0138.0-2155 using a combination of Chandra X-ray data, Multi-Unit Spectroscopic Explorer (MUSE) spectroscopy, and Hubble Space Telescope imaging.

Tidal Disruption of Super Star Clusters as the Origin of Bluish Light at the Inner Region of the Perseus Cluster Central Galaxy

The Astrophysical Journal
Relatively blue light extends beyond a spiral disk from a radius of ∼5 kpc out to ∼14 kpc from the center of NGC 1275. Analyses of its spectrum and broadband colors reveal a population of young stars having subsolar metallicities superposed on a dominant
