The Low Mass X-ray Binary-globular Cluster Connection Ii: Ngc 4472 X-ray Source Properties and Source Catalogs
We present the results of a Chandra/HST study of the point sources of the Virgo cluster giant elliptical galaxy NGC 4472. We identify 144 X-ray point sources outside the nuclear region, 72 of which are located within the HST fields. The optical data show 1102 sources, of which 829 have colors consistent with being globular clusters (with only 4 in the restricted central 10” region). Thirty matc...

augmentation of the maxillary sinus is a highly predictable and effective procedure to increase bone volume in the posterior maxilla. Success rates are equal to or better than that of all implants placed in nongrafted maxillary bone in or out of the sinus. Consequently, even in situations where the interocclusal dimension is normal or only moderately increased due to loss of bone height, bone a...
متن کاملUnderstanding Classes using XRay Views
Understanding the internal workings of classes is a key prerequisite to maintaining an object-oriented software system. Unfortunately, classical editing and browsing tools offer mainly linear and textual views of classes and their implementation. These views fail to expose the semantic relationships between the internal parts of a class. We propose XRay views —a technique based on Concept Analy...
متن کاملGlobular Cluster Metallicity Subpopulations in NGC 4472
Bimodality is a common feature of globular cluster (GC) color distributions in galaxies. Although it is well known that the GC system of the Milky Way is bimodal in metallicity, this has yet to be directly demonstrated for an elliptical galaxy. We use Lick index measurements from the literature to derive metallicities for 47 GCs in the giant Virgo elliptical galaxy NGC 4472. The resulting distr...
متن کاملThe Low - Mass X - Ray Binary - Globular Cluster Connection in Ngc 4472 1
We have analyzed the low mass X-ray binary (LMXB) candidates in a Chandra observation of the giant elliptical galaxy NGC 4472. In a region observed by the Hubble Space Telescope (HST), approximately 40% of the bright (LX&10 37 ergs s) LMXBs are associated with optically identified globular clusters (GC). This is significantly higher than the fraction of bright LMXBs in Galactic GCs and confirms...
