Friends. The Chandra Source Catalog version 2.1 has been released! This is a very rich and exciting dataset for astronomical discovery, and for data-driven exploration, regardless of whether you are an X-ray astronomer or not. Enjoy it! cxc.cfa.harvard.edu/csc/

You never know what your neighbors might be up to. Irregular dwarf galaxy IC1613 has been a member of the Local Group since time immemorial, and here Chandra and VLA observations (see bibcode 2022AJ....163...66S) reveal it has a "complex bubble region." Sounds like fun.
In 2024ApJ...961...26R, Rangelov+24 report on Chandra observations of 13 Fermi LAT sources from the 4th Fermi LAT 14 year Catalog, or 4FGL. Two of the sources (4FGL J2041.1+4736 and 4FGL J1358.3-6026) are extended. Here are images of them.
Among other useful things, @ChandraArchive CDC DOIs allow us to create cool data viz showing how @chandraxray observations (red), collections (blue) and publications (green) are linked to each other. We look forward to these networks growing more complex and interconnected!
Our article in the recently published @chandraxray Newsletter issue 34 describes how DOIs can be used to greatly facilitate the citation of Chandra data in your papers! Have a look, won't you? cxc.cfa.harvard.edu/newsletters/ne…
Chandra ACIS-S ObsID 4799 was part of a proposal to to observe a sample of 28 AGNs from KISS (KPNO International Spectroscopic Survey) to assess their X-ray emission characteristics and establish the local AGN X-ray luminosity function. Here is a picture of KISS F1610-1418.
Today is the 130th anniversary of the birthday of astrophysicist Megndad Saha, whose eponymous ionisation equation aided immeasurably in the spectral classification of stars.
