Detection of X-ray emission from galaxies inside the Bootes void

We report the X-ray properties of Bootes void galaxies detected by the ROSA T All-Sky Survey (RASS). By searching the fields of 26 radio and 27 emissio n-line-selected void galaxies, we have detected nine X-ray-emitting void ga laxies at greater than 2.7 sigma confidence level. Five of these nine galax ies are in the IRAS subsample. Two of the IRAS galaxies were previously ide ntified in positional cross-correlation studies of the RASS and IRAS Point Source Catalogue sources. Three of the X-ray-emitting galaxies are active g alactic nuclei (AGNs; IRAS 14288+5255, Mrk 845, and IRAS 15195+5050), three are emission-line galaxies (PC 1357+4641, CG 547, and CG 922), and the rem aining three are of unknown spectral type (IRAS 14500+4804, CG 637, and IRA S 15092+3940). The far-infrared flux levels of the AGN sources imply that m ost of the observed X-ray emissivity is from starburst activity. We have ca rried out timing and spectral analysis for the Seyfert 1 galaxy Mrk 845. Po or statistics prevents detailed analysis of the remaining sources. Only two galaxies in our sample, BHI 1514+3819 and FSS 1515+3823, were observed dur ing ROSAT pointed observations resulting in a nondetection at the 1 sigma l evel.
