Discovery of a Giant Molecular Cloud at the Midpoint of the Galactic Bar Dust Lanes: M4.7-0.8
Natalie Butterfield, Larry Morgan, Ashley Barnes +10
We present the detection of a previously unknown giant molecular cloud (GMC) located at the midpoint of the Galactic Bar Dust Lanes (M4.7--0.8), using spectral line observations ta…
Turbulent Pressure Heats Gas and Suppresses Star Formation in Galactic Bar Molecular Clouds
Andy Nilipour, Juergen Ott, David S. Meier +6
The Central Molecular Zone (CMZ) of the Milky Way is fed by gas inflows from the Galactic disk along almost radial trajectories aligned with the major axis of the Galactic bar. How…
Candidate intermediate-mass black hole discovered in an extremely young low-metallicity cluster in the tadpole galaxy KUG 1138+327
Q. Daniel Wang, Juergen Ott
We explore what unusual products a starburst of about 6% solar metallicity and a mean estimated age of ~0.5 Myr can produce in KUG 1138 + 327 at a distance of 24.5 Mpc. Chandra X-r…
The Young Ages of 70 μm-dark Clumps Inferred from Carbon Chain Chemistry
Kadin Worthen, Brian E. Svoboda, David S. Meier +4
The physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules…
