Counting Reachable Positions in a Simplified Model of Connect Four
Alistair Folster
By eliminating the win condition in the game of Connect Four and extending the board to infinite height, a rich state space of positions is obtained. We investigate the number of p…
Thermal Structure and Chemical Enrichment of the North and South Polar Spurs: Supersolar N/O and Ne/O in the X-ray Plasma
Anjali Gupta, Smita Mathur, Joshua Kingsbury +5
The North Polar Spur (NPS) is a prominent diffuse X-ray feature whose origin has remained uncertain for decades. Using a uniform analysis of archival \textit{Suzaku} and \textit{XM…
Probing the hot circumgalactic medium of external galaxies in X-ray absorption II: a luminous spiral galaxy at
Smita Mathur, Sanskriti Das, Anjali Gupta +1
The circumgalactic medium (CGM) is the most massive baryonic component of a spiral galaxy, shock heated to about K for an galaxy. The CGM of the Milky Way has…
Point source contribution to the Diffuse X-ray Background below 1 keV and its effect on our understanding of the circum-galactic medium
Sicong Huang, Nico Cappelluti, Massimiliano Galeazzi +4
We studied the spectral signature of different components of the Diffuse X-ray Background (DXB), including Local Hot Bubble (LHB), Solar Wind Charge Exchange (SWCX), Galactic Halo,…
X-Ray Detection of the Galaxy's Missing Baryons in the Circum-Galactic Medium of L Galaxies
Fabrizio Nicastro, Yair Krongold, Taotao Fang +10
The amount of baryons hosted in the disks of galaxies is lower than expected based on the mass of their dark-matter halos and the fraction of baryon-to-total matter in the universe…
The hot circumgalactic medium of the Milky-Way: new insights from XMM-Newton observations
Joy Bhattacharyya, Sanskriti Das, Anjali Gupta +2
We present XMM-Newton observations around the sightline of Mrk 421. The emission spectrum of the Milky Way circumgalactic medium (CGM) shows that a two phase model is a better fit…
