The carbon footprint of large astronomy meetings
Leonard Burtscher, Didier Barret, Abhijeet P. Borkar +5
The annual meeting of the European Astronomical Society took place in Lyon, France, in 2019, but in 2020 it was held online only due the COVID-19 pandemic. The carbon footprint of…
Timing Calibration of the NuSTAR X-ray Telescope
Matteo Bachetti, Craig B. Markwardt, Brian W. Grefenstette +13
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission is the first focusing X-ray telescope in the hard X-ray (3-79 keV) band. Among the phenomena that can be studied in this…
A hard look at local, optically-selected, obscured Seyfert galaxies
E. S. Kammoun, J. M. Miller, M. Koss +11
We study the X-ray spectra of a sample of 19 obscured, optically-selected Seyfert galaxies (Sy 1.8, 1.9 and 2) in the local universe (~Mpc), drawn from the CfA Seyfert…
Detection capabilities of the Athena X-IFU for the warm-hot intergalactic medium using gamma-ray burst X-ray afterglows
S. Walsh, S. McBreen, A. Martin-Carrillo +5
At low redshifts, the observed baryonic density falls far short of the total number of baryons predicted. Cosmological simulations suggest that these baryons reside in filamentary…
Estimating, monitoring and minimizing the travel footprint associated with the development of the Athena X-ray Integral Field Unit -- An on-line travel footprint calculator released to the science community
Didier Barret
Global warming imposes us to reflect on the way we carry research, embarking on the obligation to minimize the environmental impact of our research programs, with the reduction of…
Studying the Reflection Spectra of the New Black Hole X-ray Binary Candidate MAXI J1631-479 Observed by NuSTAR: A Variable Broad Iron Line Profile
Yanjun Xu, Fiona A. Harrison, John A. Tomsick +5
We present results from the Nuclear Spectroscopic Telescope Array (NuSTAR) observations of the new black hole X-ray binary candidate MAXI J1631-479 at two epochs during its 2018-20…
