Isolated X-ray -- infrared sources in the region of interaction of the supernova remnant IC 443 with a molecular cloud

A. M. Bykov, A. M. Krassilchtchikov, Yu. A. Uvarov +5

The nature of the extended hard X-ray source XMMU J061804.3+222732 and its surroundings is investigated using XMM-Newton, Chandra, and Spitzer observations. This source is located…

On the nature of the hard X-ray source IGR J2018+4043

A. M. Bykov, A. M. Krassilchtchikov, Yu. A. Uvarov +13

We found a very likely counterpart to the recently discovered hard X-ray source IGR J2018+4043 in the multi-wavelength observations of the source field. The source, originally disc…
