“…Suzaku (Mitsuda et al 2007) XIS (Koyama et al 2007) data were used to complement Swift/BAT spectra for 10 sources. For most of its operating time XIS was composed of three cameras, the front-illuminated (FI) XIS 0 and XIS 3 and the back-illuminated (BI) XIS 1 (hereafter BI-XIS).…”

Hard X-ray (10 keV) observations of active galactic nuclei (AGNs) can shed light on some of the most obscured episodes of accretion onto supermassive black holes. The 70-month Swift/BAT all-sky survey, which probes the 14-195 keV energy range, has currently detected 838 AGNs. We report here on the broadband X-ray (0.3-150 keV) characteristics of these AGNs, obtained by combining XMM-Newton, Swift/XRT, ASCA, Chandra, and Suzaku observations in the soft X-ray band ( 10  keV) with 70-month averaged Swift/BAT data. The nonblazar AGNs of our sample are almost equally divided into unobscured (N 10 cm H 22 2 < -) and obscured (N 10 cm H 22 2  -) AGNs, and their Swift/BAT continuum is systematically steeper than the 0.3-10 keV emission, which suggests that the presence of a high-energy cutoff is almost ubiquitous. We discuss the main X-ray spectral parameters obtained, such as the photon index, the reflection parameter, the energy of the cutoff, neutral and ionized absorbers, and the soft excess for both obscured and unobscured AGNs.

“…At the time of writing, Suzaku (Mitsuda et al 2007) is no longer operational. The observatory consisted of four coaligned Wolter-I telescopes, aimed at the X-ray Imaging Spectrometer (XIS, Koyama et al 2007) numbered 0 through 3 and sensitive in the 0.2-12 keV band.…”

IACHEC CROSS-CALIBRATION OF CHANDRA, NuSTAR, SWIFT, SUZAKU, XMM-NEWTON WITH 3C 273 ANDPKS 2155-304

et al. 2016

View full text Add to dashboard Cite

On behalf of the International Astronomical Consortium for High Energy Calibration, we present results from the cross-calibration campaigns in 2012 on 3C 273 and in 2013 on PKS 2155-304 between the then active X-ray observatories Chandra, NuSTAR, Suzaku, Swift, and XMM-Newton. We compare measured fluxes between instrument pairs in two energy bands, 1-5 keV and 3-7 keV, and calculate an average cross-normalization constant for each energy range. We review known cross-calibration features and provide a series of tables and figures to be used for evaluating cross-normalization constants obtained from other observations with the above mentioned observatories.

“…A likely candidate is the 3 He JT cryocooler being developed for SPICA [14,15], which has a cooling power of 10 mW at 1.7 K. Currently, a 4 He JT cryocooler has been developed as a flight model for the SMILES instrument onboard the International Space Station and is scheduled to operate in orbit beginning in 2009 [9]. Development of the 3 He JT cryocooler is, however, at the breadboard/engineering model level and is not mature yet to replace the LHe completely. In addition, this cryocooler needs LHe for initial cooling or it takes a long time (>50 days) to cool down from room temperature.…”

Cooling system for the soft X-ray spectrometer onboard Astro-H

The Soft X-ray Spectrometer (SXS) is a cryogenic high resolution X-ray spectrometer onboard the X-ray astronomy satellite Astro-H which will be launched in 2014. The detector array is cooled down to 50 mK using an adiabatic demagnetization refrigerator (ADR). The cooling chain from the room temperature to the ADR heat-sink is composed of superfluid liquid He, a Joule-Thomson cryocooler, and double-stage Stirling cryocoolers. It is designed to keep 30 of liquid He for more than 5 years in the normal case, and longer than 3 years even if one of the cryocoolers fails. Cryogen-free operation is also possible in the normal case. It is fully redundant from the room temperature to the ADR heat-sink.
