Discovery and Follow-up of a Nearby Galaxy from the Arecibo Zone of Avoidance Survey
Discovery Follow-up Nearby Galaxy Arecibo Zone Avoidance Survey
2011/10/13
The Arecibo L-Band Feed Array Zone of Avoidance (ALFA ZOA) Survey has discovered a nearby galaxy, ALFA ZOA J1952+1428, at a heliocentric velocity of +279 km s-1. The galaxy was discovered at low Galac...

2009/2/27
We report the observation and analysis of ionization flashes associated with the decay of meteoroids (so-called head echos) detected by the Arecibo 430 MHz radar during regular ionospheric observation...
Radiant measurement accuracy of micrometeors detected by the Arecibo 430 MHz Dual-Beam Radar
Radiant measurement micrometeors Arecibo 430 MHz Dual-Beam Radar
2009/2/25
Precise knowledge of the angle between the meteor vector velocity and the radar beam axis is one of the largest source of errors in the Arecibo Observatory (AO) micrometeor observations. In this paper...
