A Thickness of Stellar Disks of Edge-on Galaxies and Position of Their Truncation Radii
A. V. Zasov, D. V. Bizyaev
The relationship between the geometrical properties of stellar disks (a flatness and truncation radius) and the disk kinematics are considered for edge-on galaxies. It is shown tha…
Near-threshold -meson production in proton-proton collisions: With or without resonance excitations ?
K. Tsushima, K. Nakayama
We present results for the reaction studied by considering two different scenarios: with and without the inclusion of nucleon resonance excitations. The recently me…
Helium and Hydrogen Line Ratios and The Stellar Content of Compact HII Regions
S. L. Lumsden, P. J. Puxley, M. G. Hoare +2
We present observations and models of the behaviour of the HI and HeI lines between 1.6 and 2.2um in a small sample of compact HII regions. As in our previous papers on planetary n…
Simulating Observations of Dark Matter Dominated Galaxies: Towards the Optimal Halo Profile
W. J. G. de Blok, A. Bosma, S. S. McGaugh
Low Surface Brightness (LSB) galaxies are dominated by dark matter, and their rotation curves thus reflect their dark matter distribution. Recent high-resolution rotation curves su…
On the Radiation Damage of BTeV EMCAL Detector Unit
A. Borisevich, V. Dormenev, G. Drobychev +7
Hamamatsu photomultiplier tubes (PMT) and various PMT window materials were exposed to gamma irradiation. Tests were performed with absorbed doses of 1 krad and 120 krad. Initial r…
A deep VLA survey at 6 cm in the Lockman Hole
P. Ciliegi, G. Zamorani, G. Hasinger +3
We have obtained a deep radio image with the Very Large Array at 6 cm in the Lockman Hole. The noise level in the central part of the field is about 11 microJy. From these data we…
