On Odd Radio Circles as Supernova Remnants
Sumit K. Sarbadhicary, Todd A. Thompson, Laura A. Lopez +1
The origin of arcmin-sized Odd Radio Circles (ORCs) found in modern all-sky radio surveys remain uncertain, with explanations ranging from starburst/AGN-driven shocks to supernova…
The hot circumgalactic medium of the Milky Way: evidence for super-virial, virial, and sub-virial temperature, non-solar chemical composition, and non-thermal line broadening
Sanskriti Das, Smita Mathur, Anjali Gupta +1
For the first time, we present the simultaneous detection and characterization of three distinct phases at K in absorption, using deep observations tow…
X-ray sources in the 1.75 Ms Ultra Narrow Deep Field observed by XMM-Newton
M. Elías-Chávez, A. L. Longinotti, Y. Krongold +5
In this work we present the results of the survey carried out on one of the deepest X-ray fields observed by the XMM-Newton satellite. The 1.75 Ms Ultra Narrow Deep Field (XMM175UN…
Detection of a Multi-Phase Ultra-Fast Wind in the Narrow-Line Seyfert 1 Galaxy Mrk 1044
Y. Krongold, A. L. Longinotti, M. Santos-Lleo +6
We present a detailed analysis of XMM-Newton X-ray spectra of the Narrow-Line Seyfert 1 galaxy Mrk 1044. We find robust evidence for a multi-phase, ultra-fast outflow, traced by fo…
Observations of the gamma-ray emitting narrow-line Seyfert 1, SBS 0846+513, and its host galaxy
Timothy S. Hamilton, Marco Berton, Sonia Antón +9
The gamma-ray emitting galaxy SBS 0846+513 has been classified as a Narrow-Line Seyfert 1 from its spectroscopy, and on that basis it was thought likely to have a small central bla…
The host galaxy of OJ 287 revealed by optical and near-infrared imaging
K. Nilsson, J. Kotilainen, M. Valtonen +11
The BL Lacertae object OJ 287 (z = 0.306) has unique double-peaked optical outbursts every ~12 years, and it presents one of the best cases for a small-separation binary supermassi…
