  We analyze the two unclassified newly outbursting X-ray binary transients in
the galactic center, Swift J174540.7-290015 and Swift J174540.2-290037, in an
attempt to identify the nature of these sources. We engage in a thorough
spectral analysis for the two systems, by examining the fits of various
astrophysical models, in addition to assessing their light curves and power
spectra. Our results showed that Swift 15 has a low temperature blackbody
spectrum with a hard power-law tail, and Swift 37 has a broad iron line and a
small equivalent width; both transients exhibit classic spectral signatures of
black hole systems. Additionally, our observations for both sources yielded the
absence of type 1 X-ray bursting and the possible presence of low-frequency
quasi-periodic oscillations. Our finding that these two sources appear to be
black hole X-ray systems is a groundbreaking discovery, as it adds on to an
extremely small population of well-established black hole candidates in the
entire galaxy, in addition to giving the first strong indication for a
clustering of black holes within the central few parsecs of the galactic
center.
