Extended OVI haloes of starforming galaxies
E. O. Vasiliev, M. V. Ryabova, Yu. A. Shchekinov
We consider evolution of metal-enriched gas exposed to a superposition of time-dependent radiation field of a nearby starburst galaxy and nearly invariant (on timescales 100 Myr) e…
Conditions for supernovae driven galactic winds
Biman B. Nath, Yuri Shchekinov
We point out that the commonly assumed condition for galactic outflows, that supernovae (SNe) heating is efficient in the central regions of starburst galaxies, suffers from invali…
Signatures of particle decay in 21 cm absorptions from first minihalos
E. O. Vasiliev, Yu. A. Shchekinov
The imprint of decaying dark matter (DM) particles in characteristics of the "21 cm fores" -- absorptions in 21 cm from minihalos in spectra of distant radio-loud sources -- is con…
Interaction of galactic wind with halo gas and the origin of multiphase extraplanar material
Mahavir Sharma, Biman B. Nath, Indranil Chattopadhyay +1
We study the interaction of galactic wind with hot halo gas using hydrodynamical simulations. We find that the outcome of this interaction depends crucially on the wind injection d…
Superbubble breakout and galactic winds from disk galaxies
Arpita Roy, Biman B. Nath, Prateek Sharma +1
We study the conditions for disk galaxies to produce superbubbles that can break out of the disk and produce a galactic wind. We argue that the threshold surface density of superno…
