Journal of Cosmology and Astroparticle Physics, 2015 Simple models of weakly interacting massive particles (WIMPs) predict dark matter annihilations into pairs of electroweak gauge bosons, Higgses or tops, which through their subsequent cascade decays produce a spectrum of gamma rays. Intriguingly, an excess in gamma rays coming from near the Galactic center has been consistently observed in Fermi data ...

A Disk in the Galactic Center in the Past? [PDF]
, 2006 We raise the question whether in the past a disk could have existed in our Galactic Center which has disappeared now. Our model for the interaction of a cool disk and a hot corona above (Liu et al. 2004) allows to estimate an upper limit for the mass that might have been present in a putative accretion disk after a last star forming event, but would ...

Radio sources in the Chandra Galactic Bulge Survey [PDF]
, 2012 We discuss radio sources in the Chandra Galactic Bulge Survey region. By cross-matching the X-ray sources in this field with the NRAO VLA Sky Survey archival data, we find 12 candidate matches.

Massive Stars in the Galactic Center [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe present results of two studies aiming at better understanding the properties of massive stars in the Galactic Center. We focus on the youngest and oldest of the three massive clusters harboring this region, namely the Arches and central cluster.

Symposium - International Astronomical Union, 1984 The center of our Galaxy contains an extremely compact nonthermal radio source. For the first time, elongation in the source structure has been detected. The long axis is nearly aligned with the minor axis of the Galaxy. Recent high resolution observations of the ionized gas within the central 3 parsecs suggest that matter may be falling in towards the

Galactic cosmic ray modulation near the heliospheric current sheet [PDF]
, 2014 Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ...

UniverseDespite a decade’s worth of gravitational wave observations, the origin of the binary black hole (BBH) mergers detected by the LIGO–Virgo–KAGRA (LVK) collaboration remains an open question.
