We present the second ROSAT all-sky survey source catalogue, hereafter referred to as the 2RXS catalogue. This is the second publicly released ROSAT catalogue of point-like sources…
M dwarf Stars - The By-Product of X-Ray Selected AGN Candidates
Y. Bai, Y. -C. Sun, X. -T. He +5
X-ray loud M dwarfs are a major source of by-product (contamination) in the X-ray band of the multiwavelength quasar survey (MWQS). As a by-product, the low dispersion spectra of 2…
