A Characterization of the Circumstellar Gas around WD 1124-293 using Cloudy
Amy Steele, John Debes, Siyi Xu +2
Between 30 - 50% of white dwarfs (WDs) show heavy elements in their atmospheres. This "pollution" is thought to arise from the accretion of planetesimals perturbed by outer planet(…
Background Infrared Sources for Studying the Galactic Center's Interstellar Gas
T. R. Geballe, E. Lambrides, B. Schlegelmilch +5
We briefy describe the results of a K-band spectroscopic survey of over 500 highly reddened point-like objects on sightlines toward the Central Molecular Zone (CMZ) of the Galaxy.…
Super-Eddington Accretion in the WISE-Selected Extremely Luminous Infrared Galaxy W2246-0526
Chao-Wei Tsai, Peter Eisenhardt, Hyunsung Jun +8
We use optical and near-infrared spectroscopy to observe rest-UV emission lines and estimate the black hole mass of WISEA J224607.56-052634.9 (W2246-0526) at z = 4.601, the most lu…
The MALATANG Survey: the L_gas-L_IR correlation on sub-kiloparsec scale in six nearby star-forming galaxies as traced by HCN J=4-3 and HCO^+ J=4-3
Qing-Hua Tan, Yu Gao, Zhi-Yu Zhang +43
We present HCN J=4-3 and HCO^+ J=4-3 maps of six nearby star-forming galaxies, NGC 253, NGC 1068, IC 342, M82, M83, and NGC 6946, obtained with the James Clerk Maxwell Telescope as…
Molecular and Ionized Hydrogen in 30 Doradus. I. Imaging Observations
Sherry C. C. Yeh, Ernest R. Seaquist, Christopher D. Matzner +1
We present the first fully calibrated H, 1-0 S(1) image of the entire 30 Doradus nebula. The observations were conducted using the NOAO Extremely Wide-Field Infrared Imager on…
The CO Molecular Outflows of IRAS 16293-2422 Probed by the Submillimeter Array
Sherry C. C. Yeh, Naomi Hirano, Tyler L. Bourke +4
We have mapped the proto-binary source IRAS 16293-2422 in CO 2-1, 13CO 2-1, and CO 3-2 with the Submillimeter Array (SMA). The maps with resolution of 1".5-5" reveal a single small…
