Measuring Magnetic Field Strengths in Galactic Star-forming Regions via the Zeeman Effect with the SKA
Tyler L. Bourke, Tao-Chung Ching, Laura Fissel +14
Magnetic fields thread the interstellar medium from the largest to the smallest scales and play an important role in molecular cloud evolution and star formation. Quantifying this…
Origin of gas in the Magellanic Bridge: MeerKAT detection of HI 21-cm absorption
A. P. M. Morelli, J. Kerp, N. Gupta +6
HI 21-cm absorption lines are investigated to determine the origin of the neutral atomic hydrogen (HI) of the Magellanic Bridge (MB). Using the MeerKat Absorption Line Survey (MALS…
The MeerKAT Absorption Line Survey (MALS) data release 3: Cold atomic gas associated with the Milky Way
N. Gupta, J. Kerp, S. A. Balashev +15
We present results of a blind search for Galactic HI 21-cm absorption lines toward 19130 radio sources, using 390 pointings of MALS, each pointing centered on a source brighter tha…
The discovery and evolution of a radio continuum and excited-OH spectral-line outburst in the nearby galaxy NGC 660
C. J. Salter, T. Ghosh, R. F. Minchin +4
Arecibo 305-m Telescope observations between 2008 and 2018 detected a radio continuum and spectral-line outburst in the nearby galaxy, NGC 660. Excited-OH maser emission/absorption…
An Outflow-Driven Water Maser Associated with Positive Black Hole Feedback in the Dwarf Galaxy Henize 2-10
Hansung B. Gim, Amy E. Reines, Emmanuel Momjian +1
Henize 2-10 is a dwarf galaxy experiencing positive black hole (BH) feedback from a radio-detected low-luminosity active galactic nucleus. Previous Green Bank Telescope (GBT) obser…
MALS discovery of a rare HI 21-cm absorber at : origin of the absorbing gas in powerful AGN
P. P. Deka, N. Gupta, H. W. Chen +14
We report a new, rare detection of HI 21-cm absorption associated with a quasar (only six known at ) here towards J2339-5523 at = 1.3531, discovered through the Mee…
