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').
