BAT AGN Spectroscopic Survey. XX. Molecular Gas in Nearby Hard-X-Ray-selected AGN Galaxies
Lamperti, Isabella; Schawinski, Kevin; Saintonge, Amelie +23 more
We present the host-galaxy molecular gas properties of a sample of 213 nearby (0.01 < z < 0.05) hard-X-ray-selected active galactic nucleus (AGN) galaxies, drawn from the 70-month catalog of Swift's Burst Alert Telescope (BAT), with 200 new CO(2-1) line measurements obtained with the James Clerk Maxwell Telescope and the Atacama Pathfinder E…
The Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER). I. Ultraviolet to Infrared Photometry of 22 Million Stars in M33
Bell, Eric F.; Lindberg, Christina W.; Williams, Benjamin F. +18 more
We present panchromatic resolved stellar photometry for 22 million stars in the Local Group dwarf spiral Triangulum (M33), derived from Hubble Space Telescope observations with the Advanced Camera for Surveys in the optical (F475W, F814W), and the Wide Field Camera 3 in the near-ultraviolet (F275W, F336W) and near-infrared (F110W, F160W) bands. Th…
Molecules with ALMA at Planet-forming Scales (MAPS). XIX. Spiral Arms, a Tail, and Diffuse Structures Traced by CO around the GM Aur Disk
Zhang, Ke; Kalas, Paul; Wilner, David J. +28 more
The concentric gaps and rings commonly observed in protoplanetary disks in millimeter continuum emission have lent the impression that planet formation generally proceeds within orderly, isolated systems. While deep observations of spatially resolved molecular emission have been comparatively limited, they are increasingly suggesting that some dis…
Introducing piXedfit: A Spectral Energy Distribution Fitting Code Designed for Resolved Sources
Wu, Po-Feng; Lin, Yen-Ting; Abdurro'uf +1 more
We present piXedfit, pixelized spectral energy distribution (SED) fitting, a Python package that provides tools for analyzing spatially resolved properties of galaxies using multiband imaging data alone or in combination with integral field spectroscopy (IFS) data. It has six modules that can handle all tasks in the spatially resolved SED fitting.…
Molecules with ALMA at Planet-forming Scales. XX. The Massive Disk around GM Aurigae
Zhang, Ke; Wilner, David J.; Ménard, François +25 more
Gas mass remains one of the most difficult protoplanetary disk properties to constrain. With much of the protoplanetary disk too cold for the main gas constituent, H2, to emit, alternative tracers such as dust, CO, or the H2 isotopologue HD are used. However, relying on disk mass measurements from any single tracer requires a…
Molecules with ALMA at Planet-forming Scales (MAPS). XVII. Determining the 2D Thermal Structure of the HD 163296 Disk
Zhang, Ke; Wilner, David J.; Ménard, François +26 more
Understanding the temperature structure of protoplanetary disks is key to interpreting observations, predicting the physical and chemical evolution of the disk, and modeling planet formation processes. In this study, we constrain the two-dimensional thermal structure of the disk around the Herbig Ae star HD 163296. Using the thermochemical code RA…
An ACA Survey of [C I] 3P1-3P0, CO J = 4 - 3, and Dust Continuum in Nearby U/LIRGs
Ho, Luis C.; Bolatto, Alberto D.; Tadaki, Ken-ichi +11 more
We present the results of surveying [C I] 3P1-3P0, 12CO J = 4 - 3, and 630 µm dust continuum emission for 36 nearby ultra/luminous infrared galaxies (U/LIRGs) using the Band 8 receiver mounted on the Atacama Compact Array of the Atacama Large Millimeter/submillimeter Array. We describe t…
TIMES. I. A Systematic Observation in Multiple Molecular Lines toward the Orion A and Ophiuchus Clouds
Cho, Jungyeon; Choi, Minho; Choi, Yunhee +16 more
We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the J = 1-0 lines of 13CO, C18O, HCN, HCO+, and N2H+ and the J = 2-1 line of CS. The fully sampled maps with uniform noise levels are used to create moment maps. The variations of the line intens…
The HASHTAG Project: The First Submillimeter Images of the Andromeda Galaxy from the Ground
Ho, Luis C.; Lee, Chien-Hsiu; Clark, Christopher J. R. +46 more
Observing nearby galaxies with submillimeter telescopes on the ground has two major challenges. First, the brightness is significantly reduced at long submillimeter wavelengths compared to the brightness at the peak of the dust emission. Second, it is necessary to use a high-pass spatial filter to remove atmospheric noise on large angular scales, …
Census of High- and Medium-mass Protostars. V. CO Abundance and the Galactic XCO Factor
Pitts, Rebecca L.; Barnes, Peter J.
We present the second dust continuum data release in the Census of High- and Medium-mass Protostars (CHaMP), expanding the methodology trialed in Pitts et al. to the entire CHaMP survey area (280° < ℓ < 300°, - 4° < b < + 2°). This release includes maps of dust temperature (Td), H2 column density ( ${N}_{{{\rm{H}}…
