Andromeda IV, a solitary gas-rich dwarf galaxy
I. D. Karachentsev, Jayaram. N. Chengalur, R. B. Tully +4
Observations are presented of the isolated dwarf irregular galaxy And IV made with the Hubble Space Telescope Advanced Camera for Surveys and the Giant Metrewave Radio Telescope in…
Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters II. Physical Properties of dE Progenitor Candidates
S. M. Crawford, Gregory D. Wirth, M. A. Bershady +1
Luminous Compact Blue Galaxies (LCBGs) are an extreme star-bursting population of galaxies that were far more common at earlier epochs than today. Based on spectroscopic and photom…

We present and make publicly available the first data release (DR1) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ) survey. The KODIAQ survey is aime…
The Event Horizon of M87
Avery E. Broderick, Ramesh Narayan, John Kormendy +3
The 6 billion solar mass supermassive black hole at the center of the giant elliptical galaxy M87 powers a relativistic jet. Observations at millimeter wavelengths with the Event H…
An Optical Survey of the Partially Embedded Young Cluster in NGC 7129
S. E. Dahm, L. A. Hillenbrand
NGC 7129 is a bright reflection nebula located in the molecular cloud complex near l=105.4, b=+9.9, about 1.15 kpc distant. Embedded within the reflection nebula is a young cluster…
