COMAP Galactic Science I: Observations of Spinning Dust Emission at 30GHz in Dark Clouds Surrounding the λ-Orionis Hii Region
Stuart E. Harper, Clive Dickinson, Kieran A. Cleary +15
Anomalous Microwave Emission (AME) is a major component of Galactic emission in the frequency band 10 to 60 GHz and is commonly modelled as rapidly rotating spinning dust grains. T…
GBT/Argus Observations of Molecular Gas in the Inner Regions of IC 342
Jialu Li, Andrew I Harris, Erik Rosolowsky +9
We report observations of the ground state transitions of CO, CO CO, HCN, and HCO at 88-115 GHz in the inner region of the nearby galaxy IC 342. These data…
COMAP Early Science: VIII. A Joint Stacking Analysis with eBOSS Quasars
Delaney A. Dunne, Kieran A. Cleary, Patrick C. Breysse +22
We present a new upper limit on the cosmic molecular gas density at obtained using the first year of observations from the CO Mapping Array Project (COMAP). COMAP data…
COMAP Early Science: VI. A First Look at the COMAP Galactic Plane Survey
Thomas J. Rennie, Stuart E. Harper, Clive Dickinson +29
We present early results from the COMAP Galactic Plane Survey conducted between June 2019 and April 2021, spanning in Galactic longitude and $|b|<1.\!\!^{\…
An Ammonia Spectral Map of the L1495-B218 Filaments in the Taurus Molecular Cloud: II CCS & HCN Chemistry and Three Modes of Star Formation in the Filaments
Young Min Seo, Liton Majumdar, Paul F. Goldsmith +22
We present deep CCS and HCN observations of the L1495-B218 filaments in the Taurus molecular cloud obtained using the K-band focal plane array on the 100m Green Bank Telescope.…
Cross-correlating Carbon Monoxide Line-intensity Maps with Spectroscopic and Photometric Galaxy Surveys
Dongwoo T. Chung, Marco P. Viero, Sarah E. Church +15
Line-intensity mapping (LIM or IM) is an emerging field of observational work, with strong potential to fit into a larger effort to probe large-scale structure and small-scale astr…
