Galactic winds driven by cosmic ray streaming
- M. Uhlig, C. Pfrommer, +7 authors Zauari Heidelberg
- Physics
- 5 March 2012
Galactic winds are observed in many spiral galaxies with sizes from dwarfs up to the Milky Way, and they sometimes carry a mass in excess of that of newly formed stars by up to a factor of 10.… Expand
In a hot bubble: why does superbubble feedback work, but isolated supernovae do not?
- P. Sharma, A. Roy, B. Nath, Y. Shchekinov
- Physics
- 26 February 2014
Using idealized one-dimensional Eulerian hydrodynamic simulations, we contrast the behaviour of isolated supernovae with the superbubbles driven by multiple, collocated supernovae. Continuous energy… Expand
X-ray and SZ constraints on the properties of hot CGM
- Priyanka Singh, S. Majumdar, B. Nath, J. Silk
- Physics
- 19 January 2018
We use observations of stacked X-ray luminosity and Sunyaev–Zel’dovich (SZ) signal from a cosmological sample of ∼80 000 and 104 000 massive galaxies, respectively, with 10^12.6 ≲ M_500 ≲ 10^13 M_⊙… Expand
Heating of the intracluster medium by quasar outflows
- B. Nath, S. Roychowdhury
- Physics
- 10 February 2002
We study the possibility of quasar outflows in clusters and groups of galaxies heating the intracluster gas in order to explain the recent observation of excess entropy in this gas. We show that… Expand
On the enrichment of the intergalactic medium by galactic winds
- B. Nath, N. Trentham
- Physics
- 16 July 1997
Observations of metal lines in $\lyal$ absorption systems of small H~I column density and their ubiquitous nature suggest that the intergalactic medium (IGM) was enriched to about $Z \sim 0.01 \>… Expand
Gamma-line radiation from stellar winds in the Orion complex: a test for the theory of cosmic ray origin
- B. Nath, P. Biermann
- Physics
- 1 September 1994
Dynamical friction of radio galaxies in galaxy clusters
- B. Nath
- Physics
- 22 April 2008
The distribution of luminous radio galaxies in galaxy clusters has been observed to be concentrated in the inner region. We consider the role of dynamical friction of massive galaxies (M∼ 1012.5 M⊙),… Expand
Multiwavelength features of Fermi bubbles as signatures of a Galactic wind
- K. C. Sarkar, B. Nath, P. Sharma
- Physics
- 14 May 2015
Using hydrodynamical simulations, we show that an episode of star formation in the center of the Milky Way, with a star-formation-rate (SFR) � 0.5 M⊙ yr −1 for � 30 Myr, can produce bubbles that… Expand
