The Fermi/eROSITA Bubbles: A look into the nuclear outflow from the Milky Way
Kartick C. Sarkar
Galactic outflows are ubiquitous in galaxies containing active star formation or supermassive black hole activity. The presence of a large-scale outflow from the center of our own…
Are Odd Radio Circles virial shocks around massive galaxies? Implications for cosmic-ray diffusion in the circumgalactic medium
Shotaro Yamasaki, Kartick C. Sarkar, Zhaozhou Li
Recently, a new population of circular radio (GHz) objects have been discovered at high Galactic latitudes, called the Odd Radio Circles (ORCs). A fraction of the ORCs encirc…
Misaligned jets from Sgr A and the origin of Fermi/eROSITA bubbles
Kartick C. Sarkar, Santanu Mondal, Prateek Sharma +1
One of the leading explanations for the origin of Fermi Bubbles is a past jet activity in the Galactic center supermassive black hole Sgr A. The claimed jets are often assumed…
Fermi bubbles: the collimated outburst needed to explain forward-shock edges
Santanu Mondal, Uri Keshet, Kartick C. Sarkar +1
The bipolar, nonthermal, high-latitude lobes known as the Fermi bubbles (FBs) are thought to originate from a massive energy release near the Galactic centre (GC). We constrain the…
