The Southern HII Region Discovery Survey I: The Bright Catalog
Trey V. Wenger, John. M. Dickey, C. H. Jordan +7
The census of Galactic HII regions is vastly incomplete in the Southern sky. We use the Australia Telescope Compact Array (ATCA) to observe 4-10 GHz radio continuum and hydrogen ra…
A Galactic Plane Defined by the Milky Way HII Region Distribution
L. D. Anderson, Trey V. Wenger, W. P. Armentrout +2
We develop a framework for a new definition of the Galactic midplane, allowing for tilt (rotation about Galactic azimuth 90deg.), and roll (rotation about Galactic azimuth 0deg.) o…
Characterising the high-mass star forming filament G351.776--0.527 with Herschel and APEX dust continuum and gas observations
S. Leurini, E. Schisano, T. Pillai +13
G351.776-0.527 is among the most massive, closest, and youngest filaments in the inner Galactic plane and therefore it is an ideal laboratory to study the kinematics of dense gas a…
Spatially resolved origin of mm-wave linear polarization in the nuclear region of 3C 84
J. -Y. Kim, T. P. Krichbaum, A. P. Marscher +12
We report results from a deep polarization imaging of the nearby radio galaxy 3C84 (NGC1275). The source was observed with the Global Millimeter VLBI Array (GMVA) at 86…
G337.342-0.119 (the "Pebble"): A Cold, Dense, High-Mass Molecular Cloud with Unusually Large Linewidths and a Candidate High-Mass Star Cluster Progenitor
James M. Jackson, Yanett Contreras, Jill M. Rathborne +7
Exactly how high-mass star clusters form, especially the young massive clusters (YMCs: age Myr; mass solar masses), remains an open problem, largely because they are…
Asymmetric Line Profiles in Dense Molecular Clumps Observed in MALT90: Evidence for Global Collapse
James M. Jackson, J. Scott Whitaker, J. M. Rathborne +6
Using molecular line data from the Millimetre Astronomy Legacy Team 90 GHz Survey (MALT90), we have searched the optically thick \hcop\, line for the "blue asymmetry" spectroscopic…
Satellite galaxies in the Illustris-1 simulation: anisotropic locations around relatively isolated hosts
Tereasa G. Brainerd, Masaya Yamamoto
We investigate the locations of satellite galaxies in the z = 0 redshift slice of the hydrodynamical Illustris-1 simulation. As expected from previous work, the satellites are dist…
A possible observational bias in the estimation of the virial parameter in virialized clumps
A. Traficante, Y. -N. Lee, P. Hennebelle +3
The dynamics of massive clumps, the environment where massive stars originate, is still unclear. Many theories predict that these regions are in a state of near-virial equilibrium,…
Satellite Galaxies in the Illustris-1 Simulation: Poor Tracers of the Mass Distribution
Tereasa G. Brainerd
Number density profiles are computed for the satellites of relatively isolated host galaxies in the Illustris-1 simulation. The mean total mass density of the hosts is well-fitted…
Green Bank Telescope Observations of 3He+: HII Regions
Dana S. Balser, T. M. Bania
During the era of primordial nucleosynthesis the light elements 2H, 3He, 4He, and 7Li were produced in significant amounts and these abundances have since been modified primarily b…
Science with an ngVLA: Radio Recombination Lines from HII Regions
Dana S. Balser, L. D. Anderson, T. M. Bania +4
The ngVLA will create a Galaxy-wide, volume-limited sample of HII regions; solve some long standing problems in the physics of HII regions; and provide an extinction-free star form…
Probing the Jets of Blazars Using the Temporal Symmetry of Their Multi-Wavelength Outbursts
Namrata Roy, Ritaban Chatterjee, Manasvita Joshi +1
We compare the rise and decay timescales of 200 long-term (weeks-months) GeV and R-band outbursts and 25 short-term (hr-day) GeV flares in a sample of 10 bl…
RELICS: Strong Lensing Analysis of MACS J0417.5-1154 and Predictions for Observing the Magnified High-Redshift Universe with JWST
Guillaume Mahler, Keren Sharon, Carter Fox +37
Strong gravitational lensing by clusters of galaxies probes the mass distribution at the core of each cluster and magnifies the universe behind it. MACS J0417.5-1154 at z=0.443 is…
Spatially Resoved 12CO(2-1)/12CO(1-0) in the Starburst Galaxy NGC 253: Assessing Optical Depth to Constrain the Molecular Mass Outflow Rate
Laura K. Zschaechner, Alberto D. Bolatto, Fabian Walter +9
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 12CO(1-0) and 12CO(2-1) in the central 40" (680 pc) of the nuclear starburst galaxy NGC 253, includin…
The Radio Ammonia Mid-Plane Survey (RAMPS) Pilot Survey
Taylor Hogge, James Jackson, Ian Stephens +11
The Radio Ammonia Mid-Plane Survey (RAMPS) is a molecular line survey that aims to map a portion of the Galactic midplane in the first quadrant of the Galaxy (l = 10 deg - 40 deg,…
A Galaxy-Scale Fountain of Cold Molecular Gas Pumped by a Black Hole
Grant R. Tremblay, Françoise Combes, J. B. Raymond Oonk +36
We present ALMA and MUSE observations of the Brightest Cluster Galaxy in Abell 2597, a nearby (z=0.0821) cool core cluster of galaxies. The data map the kinematics of a three billi…
Hydrogen Radio Recombination Line Emission from M51 and NGC628
Matteo Luisi, L. D. Anderson, T. M. Bania +3
We report the discovery of hydrogen radio recombination line (RRL) emission from two galaxies with star formation rates (SFRs) similar to that of the Milky Way: M51 and NGC628. We…
