A 260 pc resolution ALMA map of HCN(1-0) in the galaxy NGC 4321
Lukas Neumann, Frank Bigiel, Ashley T. Barnes +24
The star formation rate (SFR) is tightly connected to the amount of dense gas in molecular clouds. However, it is not fully understood how the relationship between dense molecular…
Detection of the diffuse HI emission in the Circumgalactic Medium of NGC 891 and NGC 4565
Sanskriti Das, Amy Sardone, Adam K. Leroy +5
We present detections of 21-cm emission from neutral hydrogen (HI) in the circumgalactic medium (CGM) of the local edge-on galaxies NGC 891 and NGC 4565 using the Robert C. Byrd Gr…
A z=0 Multi-wavelength Galaxy Synthesis I: A WISE and GALEX Atlas of Local Galaxies
Adam K. Leroy, Karin M. Sandstrom, Dustin Lang +8
We present an atlas of ultraviolet and infrared images of ~15,750 local (d < 50 Mpc) galaxies, as observed by NASA's WISE and GALEX missions. These maps have matched resolution (FW…
EMPIRE: The IRAM 30-m Dense Gas Survey of Nearby Galaxies
María J. Jiménez-Donaire, F. Bigiel, A. K. Leroy +14
We present EMPIRE, an IRAM 30-m large program that mapped mm dense gas tracers at kpc resolution across the whole star-forming disk of nine nearby, massive…
Dense gas is not enough: environmental variations in the star formation efficiency of dense molecular gas at 100pc scales in M51
M. Querejeta, E. Schinnerer, A. Schruba +17
It remains unclear what sets the efficiency with which molecular gas transforms into stars. Here we present a new VLA map of the spiral galaxy M51 in 33GHz radio continuum, an exti…
Do Spectroscopic Dense Gas Fractions Track Molecular Cloud Surface Densities?
Molly J. Gallagher, Adam K. Leroy, Frank Bigiel +22
We use ALMA and IRAM 30-m telescope data to investigate the relationship between the spectroscopically-traced dense gas fraction and the cloud-scale (120 pc) molecular gas surface…
