The inauguration of the HAWC gamma-ray Observatory

by Alberto Carramiñana, HAWC spokesperson for Mexico

The High Altitude Water Cherenkov (HAWC) gamma-ray observatory was inaugurated on Friday 20th of March 2015, at its 4100m altitude site of Sierra Negra, Puebla, Mexico. HAWC is a large field of view gamma-ray detector with the unique ability to permanently monitor 1.8 Sr, performing a daily survey of 2/3 of the sky with a sensitivity level able to detect the Crab nebula in a single transit. The HAWC observatory is formed by an array of 300 individual water Cherenkov detectors of 7.2 meter of diameter and 5m height instrumented with four photomultipliers each. HAWC started scientific operations with 1/3 of the array in August 2013, obtaining in 10 months an exposure of the TeV comparable to that obtained by Milagro between 1999 and 2008. The inauguration event marks the beginning of a ten year full operations phase.

The HAWC inauguration ceremony was headed by Enrique Cabrero, director of the CONACYT in Mexico with the representation of the President of Mexico, and by Dr. France Cordova, director of the National Science Foundation (NSF). The development of HAWC was sponsored by CONACYT, NSF and the Department of Energy of the US. The HAWC collaboration unites 120 researchers located in 30 institutions of Mexico and the United States, together with associated members in Poland and Costa Rica.

Chandra X-ray Observatory

by Edward M. Mattison (CXC Deputy Manager & HEAD Deputy for Administration, CfA)

In November 2014 the Chandra X-ray Center (CXC) hosted a symposium, 15 Years of Science with Chandra, marking 15 years of successful and productive operation of the Chandra X-ray Observatory. Abstracts, presentations and posters are available at and

An engineering study of the full Chandra spacecraft completed in 2014 indicated that there are no known impediments to at least 25 years of Observatory operation. We look forward to another 10 years of Chandra operation and exciting scientific discoveries.
A team using Chandra has discovered an intermediate-mass black hole (IMBH) in the spiral galaxy NGC 2276 (see

The Cycle 17 peer review of proposals for Chandra observations will be held in June 2015, and results will be released in July. (Proposal submissions closed on 17 March 2015.)

The CXC is a sponsor of a workshop on Charge Exchange X-rays in Current and Future Astrophysical Researches, to be held in Cambridge, MA 13-15 April 2015 (see

The CXC will hold a workshop on the Universe in High Resolution X-ray Spectra, 11-14 August 2015 in Cambridge, Massachusetts. See
