Obscured and powerful AGN and starburst activities at z~3.5
M. Polletta, A. Omont, S. Berta +9
We report the discovery of two sources at z=3.867 and z=3.427 that exhibit powerful starburst and AGN activities. They benefit from data from radio to X rays from the CFHTLS-D1/SWI…
Night sky at the Indian Astronomical Observatory during 2000-2008
C. S. Stalin, M. Hegde, D. K. Sahu +4
We present an analysis of the optical night sky brightness and extinction coefficient measurements in UBVRI at the Indian Astronomical Observatory (IAO), Hanle, during the period 2…
Multiband optical monitoring of the blazars S5 0716+714 and BL Lacertae
C. S. Stalin, Gopal-Krishna, Ram Sagar +3
We report results of multiband optical monitoring of two well known blazars, S5 0716+714 and BL Lacertae, carried out in 1996 and 2000-01 with an aim to study optical variations on…
POINT-AGAPE Pixel Lensing Survey of M31 : Evidence for a MACHO contribution to Galactic Halos
S. Calchi Novati, S. Paulin-Henriksson, J. An +15
The POINT-AGAPE collaboration is carrying out a search for gravitational microlensing toward M31 to reveal galactic dark matter in the form of MACHOs (Massive Astrophysical Compact…
Long-term optical photometric monitoring of the quasar SDSS J153259.96-003944.1
C. S. Stalin, R. Srianand
We report optical Cousins R and I band monitoring observations of the high redshift (z = 4.67) QSO SDSS J153259.96-003944.1 that does not show detectable emission lines in its opti…
The POINT-AGAPE survey II: An Unrestricted Search for Microlensing Events towards M31
V. Belokurov, J. An, N. W. Evans +16
An automated search is carried out for microlensing events using a catalogue of 44554 variable superpixel lightcurves derived from our three-year monitoring program of M31. Each st…
