High-quality Extragalactic Legacy-field Monitoring (HELM) with DECam
Ming-Yang Zhuang, Qian Yang, Yue Shen +45
High-quality Extragalactic Legacy-field Monitoring (HELM) is a long-term observing program that photometrically monitors several well-studied extragalactic legacy fields with the D…
Optical Variability of Quasars with 20-Year Photometric Light Curves
Zachary Stone, Yue Shen, Colin J. Burke +52
We study the optical photometric variability of a sample of 190 quasars within the SDSS Stripe 82 region that have long-term photometric coverage during with…
CARMA = 1 cm Spectral Line Survey of Orion-KL
Douglas N. Friedel, Leslie W. Looney
Orion-KL is a well known high mass star forming region that has long been the target of spectral line surveys and searches for complex molecules. One spectral window where the regi…
Observational Results of a Multi-Telescope Campaign in Search of Interstellar Urea [(NH)CO]
Anthony J. Remijan, Lewis E. Snyder, Brett A. McGuire +10
In this paper, we present the results of an observational search for gas phase urea [(NH)CO] observed towards the Sgr B2(N-LMH) region. We show data covering urea transitio…
Complex Organic Molecules at High Spatial Resolution Toward Orion-KL I: Spatial Scales
Susanna L. Widicus Weaver, Douglas N. Friedel
Here we present high spatial resolution (<1 arcsecond) observations of molecular emission in Orion-KL conducted using the Combined Array for Research in Millimeter-Wave Astronomy (…
Complex Organic Molecules at High Spatial Resolution Toward Orion-KL II: Kinematics
D. N. Friedel, S. L. Widicus Weaver
It has recently been suggested that chemical processing can shape the spatial distributions of complex molecules in the Orion-KL region and lead to the nitrogen-oxygen "chemical di…
