CIAO: Chandra's Data Analysis System for X-Ray Astronomy and Beyond
Antonella Fruscione, Jonathan McDowell, Douglas Burke +13
The Chandra Interactive Analysis of Observations (CIAO) software, developed by the Chandra X-ray Center, has been the data analysis package for the Chandra X-ray Observatory since…
Optical dimming of RW Aur associated with an iron rich corona and exceptionally high absorbing column density
Hans Moritz Günther, T. Birnstiel, D. P. Huenemoerder +7
RW Aur is a binary system composed of two young, low-mass stars. The primary, RW Aur A, has undergone visual dimming events (~mag) in 2011, 2014-16, and 2017-2018. Visual…
Optical Spectral Variability of the Very-High-Energy Gamma-Ray Blazar 1ES 1011+496
M. Boettcher, B. Hivick, J. Dashti +10
We present results of five years of optical (UBVRI) observations of the very-high-energy gamma-ray blazar 1ES 1011+496 at the MDM Observatory. We calibrated UBVRI magnitudes of fiv…
WEBT multiwavelength monitoring and XMM-Newton observations of BL Lacertae in 2007-2008. Unveiling different emission components
C. M. Raiteri, M. Villata, A. Capetti +8
In 2007-2008 we carried out a new multiwavelength campaign of the Whole Earth Blazar Telescope (WEBT) on BL Lacertae, involving three pointings by the XMM-Newton satellite, to stud…
A new activity phase of the blazar 3C 454.3. Multifrequency observations by the WEBT and XMM-Newton in 2007-2008
C. M. Raiteri, M. Villata, V. M. Larionov +2
We present and analyse the WEBT multifrequency observations of 3C 454.3 in the 2007-2008 observing season, including XMM-Newton observations and near-IR spectroscopic monitoring, a…
The high activity of 3C 454.3 in autumn 2007. Monitoring by the WEBT during the AGILE detection
C. M. Raiteri, M. Villata, W. P. Chen +5
The quasar-type blazar 3C 454.3 underwent a phase of high activity in summer and autumn 2007, which was intensively monitored in the radio-to-optical bands by the Whole Earth Blaza…
