Low-Frequency Recombination Lines from Galaxies and AGN over Cosmic Time
Kimberly L. Emig, Sergei Balashev, Francoise Combes +10
Radio recombination lines (RRLs) at low frequencies (<10 GHz) can provide a multi-phase view of interstellar gas in nearby galaxies, absorption-line-systems, and AGN. Hydrogen RRLs…
The VLA Frontier Fields Survey: A 6GHz High-resolution Radio Survey of Abell2744
Esteban A. Orozco, Eric F. Jiménez-Andrade, Eric J. Murphy +5
We present 6GHz radio continuum observations of the galaxy cluster Abell 2744 () obtained with the Karl G. Jansky Very Large Array (VLA) as part of the VLA Frontier Fiel…
CHILES XII: The H I evolution of Luminous Compact Blue Galaxies between 0<z<0.48
H. Arlow, D. J. Pisano, M. A. Bershady +6
We study the evolution of Luminous Compact Blue Galaxies (LCBGs) by making use of H I emission line data provided by the full 856 h COSMOS H I Large Extragalactic Survey (CHILES),…
Unveiling Dominant Toroidal Magnetic Fields in a Protostellar Outflow
Tao-Chung Ching, Zhi-Yun Li, Qizhou Zhang +6
Magnetic fields play a fundamental role in the formation of protostellar winds. In the magneto-centrifugal models, poloidal magnetic fields launch winds from accretion disks, and f…
High resolution observations of 'dark' neutral hydrogen clouds in the Virgo cluster with the Very Large Array
Robert Minchin, Rhys Taylor, Emmanuel Momjian +2
We have observed six `dark' neutral hydrogen (HI) clouds discovered in the Virgo cluster by the Arecibo Galaxy Environment Survey (AGES) with the Karl G. Jansky Very Large Array (V…
CHILES XI: Resolved HI morphologies and the evolution of the H2/HI ratio over the last five billion years
J. Blue Bird, N. Luber, H. B. Gim +8
We present the neutral gas morphology of four galaxies from z = 0.22 to 0.47 obtained with the COSMOS HI Large Extragalactic Survey (CHILES). The HI is resolved at the highest reds…
