Gamma-rays from the circumgalactic medium of M31

Manami Roy, Biman B. Nath

We discuss the production of -rays from cosmic rays (CR) in the circumgalactic medium (CGM) of Andromeda (M31) in light of the recent detection of -rays from an annular regio…

Constraints on cosmic rays in the Milky Way circumgalactic medium from OVIII observations

Manami Roy, Biman B. Nath

We constrain the cosmic ray (CR) population in the circumgalactic medium (CGM) of Milky Way by comparing the observations of absorption lines of OVIII ion with predictions from ana…

A panoramic view of the circumgalactic medium in the photoionized precipitation model

Manami Roy, Biman B. Nath, G. M. Voit

We consider a model of the circumgalactic medium (CGM) in which feedback maintains a constant ratio of cooling time to freefall time throughout the halo, so that the entire CGM is…

Gamma-ray and radio background constraints on cosmic rays in Milky Way circumgalactic medium

Ranita Jana, Manami Roy, Biman B. Nath

We study the interaction of cosmic rays (CRs) with the diffuse circumgalactic gas of Milky Way (MW) galaxy that results in hadronic ray emission and radio synchrotron emission.…

X-ray orbital modulation of a white dwarf accreting from an L dwarf: The system SDSS J121209.31+013627.7

B. Stelzer, D. de Martino, S. L. Casewell +2

In an XMM-Newton observation of the binary SDSS J121209.31+013627.7, consisting of a white dwarf and an L dwarf, we detect X-ray orbital modulation as proof of accretion from the s…
