Cross-calibration of the X-ray Instruments onboard the Chandra, INTEGRAL, RXTE, Suzaku, Swift, and XMM-Newton Observatories using G21.5-0.9
Masahiro Tsujimoto, Matteo Guainazzi, Paul P. Plucinsky +7
Context. The Crab nebula has been used as a celestial calibration source of the X-ray flux and spectral shape for many years by X-ray astronomy missions. However, the object is oft…
Short Timescale Coronal Variability in Capella
Vinay L. Kashyap, Jennifer Posson-Brown
We analyze 205 ks of imaging data of the active binary, Capella, obtained with the Chandra High Resolution Camera Imager (HRC-I) to determine whether Capella shows any variability…
Dark Supergiant: Chandra's Limits on X-rays from Betelgeuse
Jennifer Posson-Brown, Vinay L. Kashyap, Deron O. Pease +1
We have analyzed Chandra calibration observations of Betelgeuse (alpha Ori, M2Iab, m_V=0.58, 131 pc) obtained at the aimpoint locations of the HRC-I (8 ks), HRC-S (8 ks), and ACIS-…
Chandra Observations of the X-ray Point Source Population in NGC 4636
Jennifer Posson-Brown, Somak Raychaudhury, William Forman +2
We present the X-ray point source population in the nearby Virgo elliptical galaxy NGC 4636 from 3 Chandra/ACIS observations, totaling 193 ks, taken over 3 years. Using wavelet dec…
Gas and Stars in an HI-Selected Galaxy Sample
J. L. Rosenberg, S. E. Schneider, J. Posson-Brown
We present the results of a J-band study of the HI-selected Arecibo Dual-Beam Survey and Arecibo Slice Survey galaxy samples using the 2 Micron All-Sky Survey data. We find that th…
