The authors have used HST/WFPC2 to observe the optical jet of the two extragalactic radio sources PKS 0521-365 (z = 0.055) and 3C 371 (z = 0.050). For PKS 0521...
Optical Linear Polarization in the Case of Two Supernovae Associated to X-ray Flashes: XRF060218/SN2006aj and XRF080109/SN2008D
We present the polarization monitoring carried out for two SNe associated with GRBs: XRF060218/SN2006aj and XRF080109/SN2008D. For XRF060218/SN2006aj we...
We present results from a project focused on searching optical microvariabilty (also known as ``intra-night'' variability) in type 2 - obscured - quasars...
Optical Multi-Band Analyses of Blue Compact Dwarf Galaxies
We are currently analysing image data for a large sample of blue compact dwarf galaxies (BCDs), obtained in multiple optical broad- and narrow-band filters. We...
Optical observations of GRB 060218/SN 2006aj and its host galaxy
The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z=0.033) and is the clearest example of a SN associated with a...
Optical Observations of GX 339-4 in Outburst with the Faulkes Telescope South
Further to ATel #2455 (see also ATels #2380, #2384) detailing recent INTEGRAL observations of the 2010 outburst of the black hole candidate transient source GX...
Optical observations of MAXI J0556-332 and an indication of a probable neutron star primary
We observed the new X-ray transient, MAXI J0556-332 (ATel #3102, #3103, #3104, #3106, #3110, #3112) with the Faulkes Telescope South on 17 and 18 January 2011...
Optical observations of PSR J2021+3651 with the GTC
We analyzed first optical observations of 17 kyr-old PSR J2021+3651 and its pulsar wind nebula obtained with the 10.4-m Gran Telescopio Canarias (GTC) telescope...
Optical Observations of Space Debris in GEO and in highly-eccentric Orbits
The space debris population in low Earth orbits (LEO) has been extensively studied during the last decade and reasonable models covering all size ranges were...
