Measuring the halo mass of MgII absorbers from their cross-correlation with Luminous Red Galaxies
Nicolas Bouche, M. T. Murphy, C. Peroux +1
We study the cross-correlation between 716 MgII quasar absorption systems and about 100,000 Luminous Red Galaxies (LRGs) selected from the Sloan Digital Sky Survey Data Release 3 i…
Star count analysis of the interstellar matter in the region of L1251
L. G. Balázs, P. Ábrahám, M. Kun +2
We studied the ISM distribution in and around the star forming cloud L1251 with optical star counts. A careful calculation with a maximum likelihood based statistical approach resu…
Long-term evolution of FU Orionis objects at infrared wavelengths
P. Ábrahám, Á. Kóspál, Sz. Csizmadia +3
We investigate the brightness evolution of 7 FU Orionis systems in the 1-100 micrometer wavelength range using data from the Infrared Space Observatory (ISO). The ISO measurements…
The infrared properties of the new outburst star IRAS 05436-0007 in quiescent phase
P. Ábrahám, Á. Kóspál, Sz. Csizmadia +3
We compiled and investigated the infrared/sub-mm/mm SED of the new outburst star IRAS 05436-0007 in quiescent phase. The star is a flat-spectrum source, with an estimated total lum…
