Twenty Years of Galactic Observations in Searching for Bursts of Collapse Neutrinos with the Baksan Underground Scintillation Telescope
The results of twenty-year-long Galactic observations in neutrino radiation
are summarized. Except for the recording of a neutrino signal from the
supernova SN 1987A, no Galactic bursts of collapse neutrinos have been
detected. An upper bound on the mean frequency of gravitational collapses in
our Galaxy was obtained, .Comment: latex, 7 pages, 2 eps figure
Population Synthesis for Neutron Star Systems with Intrinsic Kicks
We use a Monte Carlo binary synthesis code to model the formation and
evolution of neutron star systems including high-mass X-ray binaries, low-mass
X-ray binaries, double neutron star systems and radio pulsars. Our focus is on
the signature imprinted on such systems due to natal kicks to neutron stars
over and above that imparted by orbital motions. The code incorporates the
effect of the galactic potential (including rotation) on the velocities of
these systems. A comparison between our models and the observations leads us to
infer mean natal kicks between 400-500 km/s. Moreover, to be consistent with
all the data, we require a bimodal kick distribution with one peak in the
distribution near 0 km/s and the other above 600 km/s.Comment: 41 pages total, 24 text+tables pages, 17 figures, AASTeX, Accepted
