Chandra X-ray Observation of the Globular Cluster Glimpse-c01
We have observed the recently discovered rich star cluster GLIMPSE-C01 for 46 ks with the Chandra X-ray Observatory. Seventeen X-ray sources with luminosities & 0.6×1031 ergs s−1 were discovered, one of which is likely a quiescent low-mass X-ray binary. The spatial distribution of these X-ray sources with respect to the NIR and IR images of the cluster, combined with the luminosity and spectral...
متن کاملA Chandra X - ray observation of the globular cluster
We present a ∼19 ks Chandra ACIS-S observation of the globular cluster Terzan 1. Fourteen sources are detected within 1.4 of the cluster center with 2 of these sources predicted to be not associated with the cluster (background AGN or foreground objects). The neutron star X-ray transient, X1732−304, has previously been observed in outburst within this globular cluster with the outburst seen to ...
متن کاملThe Discovery of a Very Faint X-ray Transient in the Globular Cluster M15
We have identified an X-ray transient (hereafter M15 X-3) in the globular cluster M15 from an archival Chandra grating observation. M15 X-3 appears at an X-ray luminosity of 6 × 10 ergs s with a spectrum consistent with an absorbed power law of photon index 1.51±0.14. The object is identifiable in archival Chandra HRC-I observations with an X-ray luminosity of 2− 6× 10 ergs s and apparently sof...
متن کاملHigh-resolution x-ray imaging of a globular cluster core: compact binaries in 47Tuc.
We have obtained high-resolution (approximately 1") deep x-ray images of the globular cluster 47Tucanae (NGC 104) with the Chandra X-ray Observatory to study the population of compact binaries in the high stellar density core. A 70-kilosecond exposure of the cluster reveals a centrally concentrated population of faint (Lx approximately 10(30-33) ergs per second) x-ray sources, with at least 108...
