Optical Depth Estimates and Effective Critical Densities of Dense Gas Tracers in the Inner Parts of Nearby Galaxy Discs
M. J. Jimenez-Donaire, F. Bigiel, A. K. Leroy +17
High critical density molecular lines like HCN(1-0) or HCO+(1-0) represent our best tool to study currently star-forming, dense molecular gas at extragalactic distances. The optica…
Millimeter-Wave Line Ratios and Sub-beam Volume Density Distributions
Adam K. Leroy, Antonio Usero, Andreas Schruba +11
We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam.…
An Exploration of the Statistical Signatures of Stellar Feedback
Ryan D. Boyden, Eric W. Koch, Erik W. Rosolowsky +1
All molecular clouds are observed to be turbulent, but the origin, means of sustenance, and evolution of the turbulence remain debated. One possibility is that stellar feedback inj…
The JCMT Gould Belt Survey: First results from SCUBA-2 observations of the Cepheus Flare Region
Kate Pattle, Derek Ward-Thompson, Jason M. Kirk +57
We present observations of the Cepheus Flare obtained as part of the James Clerk Maxwell Telescope (JCMT) Gould Belt Legacy Survey (GBLS) with the SCUBA-2 instrument. We produce a…
The inner mass distribution of late-type spiral galaxies from SAURON stellar kinematic maps
Veselina Kalinova, Glenn van de Ven, Mariya Lyubenova +3
We infer the central mass distributions within 0.4-1.2 disc scale lengths of 18 late-type spiral galaxies using two different dynamical modelling approaches - the Asymmetric Drift…
The molecular gas mass of M33
P. Gratier, J. Braine, K. Schuster +15
[Abridged] Do some environments favor efficient conversion of molecular gas into stars? To answer this, we need to be able to estimate the H2 mass. Traditionally, this is done usin…
Study of velocity centroids based on the theory of fluctuations in position-position-velocity space
D. Kandel, A. Lazarian, D. Pogosyan
We study possibility of obtaining velocity spectra by studying turbulence in an optically thick medium using velocity centroids (VCs).We find that the regime of universal, i.e. ind…
CARMA Large Area Star Formation Survey: Dense Gas in the Young L1451 Region of Perseus
Shaye Storm, Lee G. Mundy, Katherine I. Lee +18
We present a 3 mm spectral line and continuum survey of L1451 in the Perseus Molecular Cloud. These observations are from the CARMA Large Area Star Formation Survey (CLASSy), which…
A Portrait of Cold Gas in Galaxies at 60pc Resolution and a Simple Method to Test Hypotheses That Link Small-Scale ISM Structure to Galaxy-Scale Processes
Adam K. Leroy, Annie Hughes, Andreas Schruba +14
The cloud-scale density, velocity dispersion, and gravitational boundedness of the interstellar medium (ISM) vary within and among galaxies. In turbulent models, these properties p…
The JCMT Gould Belt Survey: Evidence for Dust Grain Evolution in Perseus Star-forming Clumps
Michael Chun-Yuan Chen, J. Di Francesco, D. Johnstone +56
The dust emissivity spectral index, , is a critical parameter for deriving the mass and temperature of star-forming structures, and consequently their gravitational stability. T…
The JCMT Gould Belt Survey: Evidence for radiative heating and contamination in the W40 complex
D. Rumble, J. Hatchell, K. Pattle +55
We present SCUBA-2 450μm and 850μm observations of the W40 complex in the Serpens-Aquila region as part of the James Clerk Maxwell Telescope (JCMT) Gould Belt Survey (GBS) of nearb…
The EMPIRE Survey: Systematic Variations in the Dense Gas Fraction and Star Formation Efficiency from Full-Disk Mapping of M51
F. Bigiel, A. K. Leroy, M. J. Jimenez-Donaire +16
We present the first results from the EMPIRE survey, an IRAM large program that is mapping tracers of high density molecular gas across the disks of nine nearby star-forming galaxi…
Extending Velocity Channel Analysis for Studying Turbulence Anisotropies
Dinesh Kandel, Alex Lazarian, Dmitri Pogosyan
We extend the velocity channel analysis (VCA), introduced by Lazarian & Pogosyan, of the intensity fluctuations in the velocity slices of position-position-velocity (PPV) spectrosc…
Deuteration of ammonia in the starless core Ophiuchus/H-MM1
Jorma Harju, Fabien Daniel, Olli Sipilä +13
Ammonia and its deuterated isotopologues probe physical conditions in dense molecular cloud cores. With the aim of testing the current understanding of the spin-state chemistry of…
Effects of Galactic Disc Inclination and Resolution on Observed GMC Properties and Larson's Scaling Relations
Hsi-An Pan, Yusuke Fujimoto, Elizabeth J. Tasker +4
With ALMA making it possible to resolve giant molecular clouds (GMCs) in other galaxies, it is becoming necessary to quantify the observational bias on measured GMC properties. Usi…
Masses and Scaling Relations for Nuclear Star Clusters, and their Coexistence with Central Black Holes
Iskren Y. Georgiev, Torsten Böker, Natan Leigh +2
Galactic nuclei typically host either a Nuclear Star Cluster (NSC, prevalent in galaxies with masses ) or a Massive Black Hole (MBH, common in galaxies wit…
