The hidden variability of the torus in local Active Galactic Nuclei: 20 years of Chandra, XMM-Newton, and NuSTAR observations
Vittoria Elvezia Gianolli, Nuria Torres-Alba, Stefano Marchesi +9
X-ray absorption variability in active galactic nuclei (AGN) provides key constraints on the structure and dynamics of the circumnuclear obscuring medium, the so-called torus. A fr…
Optical Identification and Spectroscopy of Supernova Remnants in the Galaxy M51
P. Frank Winkler, Sadie C. Coffin, William P. Blair +2
Using a combination of ground-based and HST imaging, we have constructed a catalog of 179 supernova remnants (SNRs) and SNR candidates in the nearby spiral galaxy M51. Follow-up sp…
Exploring the Morphology and Origins of the 4C 38.41 Jet
Juan Carlos Algaba, Bindu Rani, Sang-Sung Lee +3
We study the properties of the innermost jet of the flat spectrum radio quasar 1633+382 (4C~38.41) based on VLBI data from the radio monitoring observations of the Boston Universit…
2 mm GISMO Observations of the Galactic Center. II. A Nonthermal Filament in the Radio Arc and Compact Sources
Johannes Staguhn, Richard G. Arendt, Eli Dwek +5
We have used the Goddard IRAM 2-Millimeter Observer (GISMO) with the 30 m IRAM telescope to carry out a 2 mm survey of the Galaxy's central molecular zone (CMZ). These observations…
2 mm GISMO Observations of the Galactic Center. I. Dust Emission
Richard G. Arendt, Johannes Staguhn, Eli Dwek +5
The Central Molecular Zone (CMZ), covering the inner ~1 of the Galactic plane has been mapped at 2 mm using the GISMO bolometric camera on the 30 m IRAM telescope. The $21'…
