An ultra-deep ISOCAM observation through a cluster-lens
B. Altieri, L. Metcalfe, J. P. Kneib +10
We present results of ultra-deep ISOCAM observations through a cluster-lens at 7 and 15 micron with the Infrared Space Observatory (ISO) satellite. These observations reveal a larg…
Measurement of the Multi-TeV gamma-ray Flare-Spectra of Markarian 421 and Markarian 501
F. Krennrich, S. D. Biller
The energy spectrum of Markarian~421 in flaring states has been measured from 0.3 to 10 TeV using both small zenith angle and large zenith angle observations with the Whipple Obser…
Wavelet Analysis and Lognormal Distributions in GRBs
Kevin J. Hurley, Brian McBreen, Fergus Quilligan +2
A wavelet analysis has been performed on 80 intense gamma-ray bursts GRBs) from the BATSE 3B catalog with durations longer than 2 seconds. The wavelet analysis applied novel featur…
Lognormal properties of SGR 1806-20 and the Possibility of a Quiescent Population of other SGR sources
Brian McBreen, Kevin J. Hurley
Monte Carlo simulations of long SGR event sequences based on lognormal distributions with a range of time intervals and intensity distribution parameters have been investigated. Th…
Occultation Mapping of the Central Engine in the Active Galaxy MCG -6-30-15
B. McKernan, T. Yaqoob
The colossal power output of active galactic nuclei (AGN) is believed to be fueled by the accretion of matter onto a supermassive black hole. This central accreting region of AGN h…
ISO Mid-Infrared Observations of Abell 370
L. Metcalfe, B. Altieri, H. Aussel +11
We report on the mid-IR imaging at 7 and 10 microns of the galaxy cluster Abell 370, obtained with the ISOCAM instrument onboard ESA's Infrared Space Observatory (ISO), as part of…
