First Observation of CO Emission and foreground absorption Toward the Galactic Center with JWST
J. Qiu, A. Ciurlo, M. R. Morris +11
CO is an important, stable, and abundant molecule in the Universe, but it is very difficult to detect because it has no observable pure rotational transitions. The unique sensi…
Dynamic Imprints of Colliding-wind Dust Formation from WR140
Emma P. Lieb, Ryan M. Lau, Jennifer L. Hoffman +24
Carbon-rich Wolf-Rayet binaries are a prominent source of carbonaceous dust that contribute to the dust budget of galaxies. The "textbook" example of an episodic dust producing WR…
A Dust-Scattering Model for M1-92: A Revised Estimate of the Mass Distribution and Inclination
Yun Qi Li, Mark R. Morris, Raghvendra Sahai
Preplanetary nebulae (PPNe) are formed from mass-ejecting late-stage AGB stars. Much of the light from the star gets scattered or absorbed by dust particles, giving rise to the obs…
Pinwheel Outflow induced by Stellar Mass Loss in a Coplanar Triple System
Hyosun Kim, Mark R. Morris, Jongsoo Kim +1
We develop a physical framework for interpreting complex circumstellar patterns whorled around asymptotic giant branch (AGB) stars by investigating stable, coplanar triple systems…
A First Look with JWST Aperture Masking Interferometry (AMI): Resolving Circumstellar Dust around the Wolf-Rayet Binary WR 137 beyond the Rayleigh Limit
Ryan M. Lau, Matthew J. Hankins, Joel Sanchez-Bermudez +20
We present infrared aperture masking interferometry (AMI) observations of newly formed dust from the colliding winds of the massive binary system Wolf-Rayet (WR) 137 with JWST usin…
Ground Vibrational State SiO Emission in the VLA BAaDE Survey
V. Dike, M. R. Morris, R. M. Rich +5
Using a subsample of the Bulge Asymmetries and Dynamical Evolution (BAaDE) survey of stellar SiO masers, we explore the prevalence and characteristics of SiO em…
Simultaneous X-ray and Infrared Observations of Sagittarius A*'s Variability
H. Boyce, D. Haggard, G. Witzel +11
Emission from Sgr A* is highly variable at both X-ray and infrared (IR) wavelengths. Observations over the last ~20 years have revealed X-ray flares that rise above a quiescent the…
SiO Masers in the Galactic Bulge and Disk: Kinematics from the BAaDE Survey
A. C. Trapp, R. M. Rich, M. R. Morris +4
We present the first results from the BAaDE (Bulge Asymmetries and Dynamic Evolution) survey. Though only a subset of the complete survey (2700 out of 20000 final sourc…
Nature Versus Nurture: Luminous Blue Variable Nebulae in and near Massive Stellar Clusters at the Galactic Center
Ryan M. Lau, Terry L. Herter, Mark R. Morris +1
Three Luminous Blue Variables (LBVs) are located in and near the Quintuplet Cluster at the Galactic Center: the Pistol star, G0.120-0.048, and qF362. We present imaging at 19, 25,…
Early Science with SOFIA, the Stratospheric Observatory for Infrared Astronomy
E. T. Young, E. E. Becklin, P. M. Marcum +38
The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7-m telescope, flying at altitudes…
Properties of the Compact HII Region Complex G-0.02-0.07
Elisabeth Mills, Mark R. Morris, Cornelia Lang +4
We present new extinction maps and high-resolution Paschen alpha images of G-0.02-0.07, a complex of compact HII regions located adjacent to the M-0.02-0.07 giant molecular cloud,…
