Latest MAGIC discoveries pushing redshift boundaries in VHE Astrophysics

M. Manganaro, J. Becerra González, M. Nievas +10

The search for detection of gamma-rays from distant AGNs by Imaging Atmospheric Cherenkov Telescopes (IACTs) is challenging at high redshifts, not only because of lower flux due to…

Gravitational Binary-lens Events with Prominent Effects of Lens Orbital Motion

H. Park, A. Udalski, C. Han +58

Gravitational microlensing events produced by lenses composed of binary masses are important because they provide a major channel to determine physical parameters of lenses. In thi…

OGLE-2005-BLG-153: Microlensing Discovery and Characterization of A Very Low Mass Binary

K. -H. Hwang, A. Udalski, C. Han +77

The mass function and statistics of binaries provide important diagnostics of the star formation process. Despite this importance, the mass function at low masses remains poorly kn…

OGLE 2004-BLG-254: a K3 III Galactic Bulge Giant spatially resolved by a single microlens

A. Cassan, J. -P. Beaulieu, P. Fouque +37

We present an analysis of OGLE 2004-BLG-254, a high-magnification and relatively short duration microlensing event in which the source star, a Bulge K3-giant, has been spatially re…

Evidence for a Supernova Associated with the X-ray Flash 020903

D. Bersier, A. S. Fruchter, L. -G. Strolger +24

We present ground-based and Hubble Space Telescope optical observations of the X-ray flash (XRF) 020903, covering 300 days. The afterglow showed a very rapid rise in the first day,…

Discovery of a Cool Planet of 5.5 Earth Masses Through Gravitational Microlensing

J. -P. Beaulieu, D. P. Bennett, P. Fouque +46

In the favoured core-accretion model of formation of planetary systems, solid planetesimals accumulate to build up planetary cores, which then accrete nebular gas if they are suffi…
