SNR 1987A : Spitzer data from days 6000 to 8000 revisited
Patrice Bouchet, René Gastaud, Alain Coulais +1
An excess emission has been observed by Spitzer in the [3, 5] micron range of the SNR 1987A spectrum. It is generally argued that this excess could be due to the presence of warm a…
SKYSURF-11: A New Zodiacal Light Model Optimized for Optical Wavelengths
Rosalia O'Brien, Richard G. Arendt, Rogier A. Windhorst +15
We present an improved zodiacal light model, optimized for optical wavelengths, using archival Hubble Space Telescope (HST) imaging from the SKYSURF program. The Kelsall et al. 199…
The External Heating of Dust in a Homogeneous Spherical Shell
Eli Dwek, Richard G. Arendt
We present a procedure for calculating the heating of, and the infrared emission from, dust in a homogeneous spherical shell surrounded by a spherically symmetric source of radiati…
Deep JWST/NIRCam imaging of Supernova 1987A
Mikako Matsuura, M. Boyer, Richard G. Arendt +46
JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…
A JWST Survey of the Supernova Remnant Cassiopeia A
Dan Milisavljevic, Tea Temim, Ilse De Looze +43
We present initial results from a JWST survey of the youngest Galactic core-collapse supernova remnant Cassiopeia A (Cas A), made up of NIRCam and MIRI imaging mosaics that map emi…
Detection of large-scale synchrotron radiation from the molecular envelope of the Sgr B cloud complex at the Galactic center
F. Yusef-Zadeh, M. Wardle, R. Arendt +6
We present highly sensitive measurements taken with MeerKAT at 1280 MHz as well as archival GBT, MWA and VLA images at 333, 88 and 74 MHz. We report the detection of synchrotron ra…
