With bolometric luminosities reaching Lvirgul10^45 erg/sec, the new class of SuperLuminous Supernovae (SLSNe) outshine ordinary SNe a factor 100 and represent thedeath of the most massive stars in our
The simultaneous optical-to-gamma-rays observations of blazars are key tools in understanding the nature of these sources the mechanisms of the gamma-ray emission and other features such as the origin
We propose to obtain high-resolution radio continuum emission observations with the VLBA at 1.4GHz (21-cm L band) to confirm a candidate dual QSO at z=1.87 comma a redshift that is nearer to d_commac
