Estimation of the sky radiance [PDF]

open access: yesScientific Technical Review, 2019
For the infrared prefilter model there was a need for testing the sky radiation and defining its fluctuations within the zone of neighborhood area for the current frame and tests of repeatability.

OT 060420: A Seemingly Optical Transient Recorded by All-Sky Cameras [PDF]

open access: yes, 2006
We report on a ~5th magnitude flash detected for approximately 10 minutes by two CONCAM all-sky cameras located in Cerro Pachon - Chile and La Palma - Spain. A third all-sky camera, located in Cerro Paranal - Chile did not detect the flash, and therefore

Mosaicking with cosmic microwave background interferometers [PDF]

open access: yes, 2006
Measurements of cosmic microwave background (CMB) anisotropies by interferometers offer several advantages over single-dish observations. The formalism for analyzing interferometer CMB data is well developed in the flat-sky approximation, valid for small

Stellar masses and star formation histories for 105 galaxies from the Sloan Digital Sky Survey [PDF]

open access: yes, 2002
We develop a new method to constrain the star formation histories, dust attenuation and stellar masses of galaxies. It is based on two stellar absorption-line indices, the 4000-A break strength and the Balmer absorption-line index Hδ A .
