Gravitational Lensing & Stellar Dynamics: Dark-Matter and Baryons in Early-type Galaxies to z=1
L. V. E. Koopmans
Gravitational lensing and stellar dynamics provide two complementary, nearly orthogonal, constraints on the mass distribution of early-type lens galaxies. This allows the luminous…
The radio spectrum of a quiescent stellar mass black hole
Elena Gallo, Rob Fender, Rob Hynes
Observations of V404 Cyg performed with the Westerbork Synthesis Radio Telescope at four frequencies, over the interval 1.4-8.4 GHz, have provided us with the first broadband radio…
Stellar explosions: from supernovae to gamma-ray bursts
Konstantin Postnov
Current understanding of core collapse and thermonuclear supernovae is reviewed. Recent progress in unveiling the nature of cosmic gamma-ray bursts (GRB) is discussed, with the foc…
High velocity HI in NGC 6946 and extra-planar gas in NGC 253
Rense Boomsma, Tom Oosterloo, Filippo Fraternali +2
Multi-wavelength observations of nearby spiral galaxies have shown that neutral and ionized gas are present up to a few kpc from the disk and that star formation and supernovae pro…
Stationary fluid models for the extra-planar gas in spiral galaxies
M. Barnabe', L. Ciotti, F. Fraternali +1
We show how to construct families of stationary hydrodynamical configurations that reproduce the observed vertical gradient of the rotation velocity of the extra-planar gas in spir…
Polarization signatures of strong gravity in AGN accretion discs
M. Dovciak, V. Karas, G. Matt
The effects of strong gravity on the polarization of the Compton reflection from an X-ray illuminated accretion disc are studied. The gravitational field of a rotating black hole i…
Close by Compact Objects and Recent Supernovae in the Solar Vicinity
S. B. Popov
I discuss young close-by compact objects, recent supernovae in the solar neighbourhood, and point to their connection with cosmic ray studies. Especially the role of the Gould Belt…
Star-disc interactions in a galactic centre and oblateness of the inner stellar cluster
L. Subr, V. Karas, J. -M. Hure
Structure of a quasi-stationary stellar cluster is modelled assuming that it is embedded in the gravitational field of a super-massive black hole. Gradual orbital decay of stellar…
Age-Distance diagram for close-by young neutron stars
S. B. Popov
An age--distance diagram for close-by young isolated neutron stars of different types is introduced and discussed. It is shown that such a diagram can be a useful tool for studying…
Galaxy dynamics with the Planetary Nebula Spectrograph
N. R. Napolitano, A. J. Romanowsky, N. G. Douglas +6
The Planetary Nebula Spectrograph is a dedicated instrument for measuring radial velocity of individual Planetary Nebulae (PNe) in galaxies. This new instrument is providing crucia…
IRS observations of the LMC planetary nebula SMP83
J. Bernard-Salas, J. R. Houck, P. W. Morris +3
The first observations of the infrared spectrum of the LMC planetary nebula SMP83 as observed by the recently launched Spitzer Space Telescope are presented. The high resolution R~…
Be/X-ray stars and candidates: catalogue
S. B. Popov, N. V. Raguzova
Here we present a compilation of data on Be/X-ray binaries. On the whole we include 90 objects into our catalogue. Brief comments on each object are provided.
Quenched millimetre emission from Cygnus X-1 in a soft X-ray state
S. P. Tigelaar, R. P. Fender, R. P. J. Tilanus +2
We present millimetre wavelength observations of the black hole candidate X-ray binary Cygnus X-1 which indicate a suppression, or quenching, of the emission as the source switches…
Radio Emission as a Test of the Existence of Intermediate Mass Black Holes in Globular Clusters and Dwarf Spheroidal Galaxies
Thomas J. Maccarone
We take the established relation between black hole mass, X-ray luminosity, and radio luminosity and show that intermediate mass black holes, such as those predicted to exist at th…
Correction of UBV photometry for emission lines
A. Skopal
We investigated the effect on the U, B, V magnitudes of the removal of the emission lines from the spectra of some symbiotic stars and novae during their nebular phases. We approac…
