Reverberation Measurements for 17 Quasars and the Size-Mass-Luminosity Relations in Active Galactic Nuclei
- S. Kaspi, Paul S. Smith, H. Netzer, D. Maoz, B. Jannuzi, U. Giveon
- Physics
- 25 November 1999
Correlated variations in the line and continuum emission from active galactic nuclei (AGNs) can be used to determine the size and geometry of the broad emission-line regions (BLRs). We have spectro-…
CENTRAL MASSES AND BROAD-LINE REGION SIZES OF ACTIVE GALACTIC NUCLEI. II. A HOMOGENEOUS ANALYSIS OF A LARGE REVERBERATION-MAPPING DATABASE
- B. Peterson, L. Ferrarese, A. Wandel
- Physics
- 14 July 2004
We present improved black hole masses for 35 active galactic nuclei (AGNs) based on a complete and consistent reanalysis of broad emission-line reverberation-mapping data. From objects with multiple…
THE RELATIONSHIP BETWEEN LUMINOSITY AND BROAD-LINE REGION SIZE IN ACTIVE GALACTIC NUCLEI
- S. Kaspi, D. Maoz, H. Netzer, B. Peterson, M. Vestergaard, B. Jannuzi
- Physics
- 21 April 2005
We reinvestigate the relationship between the characteristic broad-line region size (RBLR) and the Balmer emission-line, X-ray, UV, and optical continuum luminosities. Our study makes use of the best…
Reverberation Mapping of High-Luminosity Quasars: First Results
- S. Kaspi, W. Brandt, D. Maoz, H. Netzer, D. Schneider, O. Shemmer
- Physics
- 24 December 2006
Reverberation mapping of nearby active galactic nuclei (AGNs) has led to estimates of broad-line region (BLR) sizes and central object masses for some 37 objects to date. However, successful…
THE CLUSTER LENSING AND SUPERNOVA SURVEY WITH HUBBLE: AN OVERVIEW
- M. Postman, D. Coe, A. V. D. Wel
- Physics
- 16 June 2011
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a 524-orbit Multi-Cycle Treasury Program to use the gravitational lensing properties of 25 galaxy clusters to accurately constrain…
MULTIWAVELENGTH MONITORING OF THE DWARF SEYFERT 1 GALAXY NGC 4395. I. A REVERBERATION-BASED MEASUREMENT OF THE BLACK HOLE MASS
- B. Peterson, M. Bentz, A. Quillen
- Physics
- 27 June 2005
A reverberation-mapping program on NGC 4395, the least luminous known Seyfert 1 galaxy, undertaken with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope yields a measurement of…
The Supernova Delay Time Distribution in Galaxy Clusters and Implications for Type-Ia Progenitors and Metal Enrichment
- D. Maoz, K. Sharon, A. Gal-yam
- Physics
- 17 June 2010
Knowledge of the supernova (SN) delay time distribution (DTD)-the SN rate versus time that would follow a hypothetical brief burst of star formation-can shed light on SN progenitors and physics, as…
The delay-time distribution of Type Ia supernovae from Sloan II
- D. Maoz, F. Mannucci, Timothy D. Brandt
- Physics
- 3 June 2012
We derive the delay-time distribution (DTD) of Type Ia supernovae (SNe Ia) using a sample of 132 SNe Ia, discovered by the Sloan Digital Sky Survey II (SDSS2) among 66 000 galaxies with…
Long-term optical variability properties of the Palomar–Green quasars
- U. Giveon, D. Maoz, S. Kaspi, H. Netzer, Paul S. Smith
- Physics
- 18 February 1999
We present results from a monitoring programme of 42 quasars from the Palomar–Green sample. The objects were observed for seven years at the Wise Observatory, as part of a long-term effort to monitor…
Observational Clues to the Progenitors of Type Ia Supernovae
- D. Maoz, F. Mannucci, G. Nelemans
- Physics
- 2 December 2013
Type Ia supernovae (SNe Ia) are important distance indicators, element factories, cosmic-ray accelerators, kinetic-energy sources in galaxy evolution, and end points of stellar binary evolution. It…
