Star-forming regions that are visible at 3.6 μm and Hα but not in the u, g, r, i, z bands of the Sloan Digital Sky Survey are measured in five nearby spiral...
Emergence of an Ultrared, Ultramassive Galaxy Cluster Core at z = 4
Recent simulations and observations of massive galaxy cluster evolution predict that the majority of stellar mass buildup happens within cluster members by z =...
Emergence of Internetwork Magnetic Fields through the Solar Atmosphere
Internetwork (IN) magnetic fields are highly dynamic, short-lived magnetic structures that populate the interior of supergranular cells. Since they emerge all...
Emergence of Small-scale Magnetic Loops Through the Quiet Solar Atmosphere
We investigate the emergence of magnetic flux in the quiet Sun at very small spatial scales, focusing on the magnetic connection between the photosphere and...
Empirical Determination of Convection Parameters in White Dwarfs. I. Whole Earth Telescope Observations of EC14012-1446
We report on an analysis of 308.3 hr of high-speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth...
Enhanced Gas-phase Metallicities and Suppressed Outflows for Galaxies in a Rich Cluster Core at Cosmic Noon
We present the results of near-infrared spectroscopy using Keck/MOSFIRE for 23 member galaxies in the X-ray cluster XCS 2215 (z = 1.46) to investigate the...
Enhanced Hα Emission in Early-Type Galaxies Belonging to Compact Groups
The results of Hα photometry of a sample of early-type galaxies belonging to nearby compact groups are presented. Over 75% of the galaxies in the sample were...
Environment of the Submillimeter-bright Massive Starburst HFLS3 at z ~ 6.34
We describe the search for Lyman break galaxies (LBGs) near the submillimeter-bright starburst galaxy HFLS3 at z = 6.34 and a study on the environment of this...
