The interplay of Self-Interacting Dark Matter and baryons in shaping the halo evolution
Giulia Despali, Martin Sparre, Simona Vegetti +3
We use high-resolution hydrodynamical simulation to test the difference of halo properties in cold dark matter (CDM) and a self-interacting dark matter (SIDM) scenario with a const…
The physics of multiphase gas flows: fragmentation of a radiatively cooling gas cloud in a hot wind
Martin Sparre, Christoph Pfrommer, Mark Vogelsberger
Galactic winds exhibit a multiphase structure that consists of hot-diffuse and cold-dense phases. Here we present high-resolution idealised simulations of the interaction of a hot…
Highly-ionized metals as probes of the circumburst gas in the natal regions of gamma-ray bursts
K. E. Heintz, D. Watson, P. Jakobsson +18
We present here a survey of high-ionization absorption lines in the afterglow spectra of long-duration gamma-ray bursts (GRBs) obtained with the VLT/X-shooter spectrograph. Our mai…
The fraction of ionizing radiation from massive stars that escapes to the intergalactic medium
N. R. Tanvir, J. P. U. Fynbo, A. de Ugarte Postigo +38
The part played by stars in the ionization of the intergalactic medium remains an open question. A key issue is the proportion of the stellar ionizing radiation that escapes the ga…
Galaxy mergers moulding the circum-galactic medium - I. The impact of a major merger
Maan H. Hani, Martin Sparre, Sara L. Ellison +2
Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and th…
