Reverberation Mapping of High-Redshift, High-Luminosity Quasars
Shai Kaspi, Hagai Netzer, Dan Maoz +3
We present preliminary results from a reverberation mapping program to measure the Broad Line Region size in high-redshift, high-luminosity quasars. The observations are carried ou…
Optical Monitoring of NLS1s at the Wise Observatory
Ohad Shemmer, Hagai Netzer
We report the preliminary results of a spectrophotometric monitoring program of Narrow-Line Seyfert 1 galaxies conducted at the Wise Observatory in 1999. The data we collected will…
Periodic Microvariation of B416, a New LBV in M33
Ohad Shemmer, Elia M. Leibowitz, Paula Szkody
We report optical photometric and spectroscopic observations of the M33 star B416, establishing it as the fifth identified LBV in that galaxy. The B magnitude of the star varies wi…
The Discovery of a Nearby M Dwarf
Ohad Shemmer, Shai Kaspi
We report the discovery of a nearby M dwarf star, found accidentally while observing the old nova DN Gem at the Wise Observatory. The star is designated 1200-05296925 in the PMM US…
