The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA's (and other space agencies') missions studying electromagnetic radiation from extremely energetic cosmic phenomena ranging from black holes to the Big Bang. Since its merger with the Legacy Archive for Microwave Background Data Analysis (LAMBDA) in 2008, the HEASARC archive contains data obtained by high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from space missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB) radiation in the sub-mm, mm and cm bands.

Try ROSAT 3c273 1d to get ROSAT data within one degree of 3C273 or chanmaster bii>80 status='archived' to get archived Chandra observation data near the north galactic pole.

Note: For more than one target or when using any qualifier other than a mission, use quotes around targets that have embedded white space.(e.g., 'ar lac').

  • NASA Space Telescopes Pinpoint Elusive Brown Dwarf (16 Nov 2016)
    In a first-of-its-kind collaboration, NASA's Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic object. This technique is useful for finding low-mass bodies orbiting stars, such as planets. In this case, the observations revealed a brown dwarf. This study by Shvartzvald et al. has just appeared in ApJ (2016, 831, 183).
  • Starvation Diet for Black Hole Dims Brilliant Galaxy (10 Nov 2016)
    Astronomers may have solved the mystery of the peculiarly volatile behavior of a supermassive black hole (SMBH) at the center of the active galaxy Mkn 1018. Combined data from Chandra and other observatories suggest that this SMBH is no longer being fed enough fuel to make its surroundings shine brightly. After discovering the AGN's fickle nature during a survey project using ESO's Very Large Telescope (VLT), astronomers observed it with both Chandra and Hubble. Other observatories used in this study include NuSTAR and Swift. Two papers on these results have just appeared in A&A;: Husemann et al. and McElroy et al. .
  • Sgr A* Region Compact Radio Source Catalog (03 Nov 2016)
    A catalog of 318 34.5-GHz sources found in a Jansky Very Large Array A configuration observation of the Galactic Center region and their near-IR counterparts (from Yusef-Zadeh et al. 2015, ApJ, 809, 10) is now available in Browse and Xamin.
  • NASA Missions Harvest a 'Passel of Pumpkin' Stars (28 Oct 2016)
    Steven Howell and colleagues (2016, ApJ, 831, 27) using observations from NASA's Kepler and Swift missions have discovered a batch of rapidly spinning stars that produce X-rays at more than 100 times the peak levels ever seen from the sun. The stars, which spin so fast they've been squashed into pumpkin-like shapes, are thought to be the result of close binary systems where two sun-like stars merge.
  • IC 1805 Young Massive Cluster XMM-Newton Source Catalog (28 Oct 2016)
    A catalog of 191 X-ray sources found in a 49-ks XMM-Newton EPIC observation of the IC 1805 open cluster (from Rauw & Nazé 2016, A&A;, 594, A82) is now available in Browse and Xamin.
  • NuSTAR CALDB Update (25 Oct 2016)
    The NuSTAR CALibration DataBase was updated on October 25, 2016 (CALDB version 20161021). This updates the NuSTAR clock correction file to version 63, valid through 2016-10-21.
