Lucky imaging techniques implemented by the FastCam group (see http://www.iac.es/proyecto/fastcam/) at the Instituto de Astrofisica de Canarias have...
Real-time phase slopes calculations by correlations using FPGAs
ELT laser guide star wavefront sensors are planned to handle an expected amount of data to be overwhelmingly large (1600×1600 pixels at 700 fps). According to...
We report a rebrightening of the newly discovered transient MAXI J0556-332 (ATEL #3102, #3103, #3104, #3106, #3110, #3112, #3116, #3119) in optical through soft...
Recent Advances in Chromospheric and Coronal Polarization Diagnostics
I review some recent advances in methods to diagnose polarized radiation with which we may hope to explore the magnetism of the solar chromosphere and corona...
Recent Chandra and Swift Observations of New X-ray Transients in M31
We report recent observations of M31 taken with Chandra/ACIS-I on 2009-05-29.1 UT and with Swift/XRT on 2009-06-07.08 UT. In the 4ks Chandra/ACIS-I image, we...
We have been monitoring the optical counterpart of the TeV emitting binary LSI +61 303 (V615 Cas) since November 2005 with the Faulkes Telescope North (on...
We present the results of optical/near-IR observations carried out in the period Dec 1998-Dec 1999 at Spanish, Indian and New Zealand observatories. Most of the...
The authors present preliminary results of optical and infrared observations of Mk 421, during an outburst. Some of these observations are simultaneous in both...
