Detection of the Missing Baryons toward the Sightline of H1821+643
Orsolya E. Kovacs, Akos Bogdan, Randall K. Smith +2
Based on constraints from Big Bang nucleosynthesis and the cosmic microwave background, the baryon content of the high-redshift Universe can be precisely determined. However, at lo…
Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster
Akos Bogdan, Lorenzo Lovisari, Orsolya E. Kovacs +4
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large d…
The Complicated Evolution of the ACIS Contamination Layer over the Mission Life of the Chandra X-ray Observatory
Paul P. Plucinsky, Akos Bogdan, Herman L. Marshall +1
The Chandra X-ray Observatory was launched almost 19 years ago and has been delivering spectacular science over the course of its mission. The Advanced CCD Imager Spectrometer is t…
Deep Chandra observations of X-ray point sources in M87
Luan Luan, Christine Jones, William R. Forman +6
We present a study of X-ray source populations in M87, the cD galaxy of the Virgo cluster, using 12 archival {\it Chandra} observations with a total exposure of 680 ks spanni…
