Title: | Hunting for intermediate mass black holes in a sample of close dwarf spheroidal galaxies | Authors: | Nucita, Achille A. Manni, Luigi DE PAOLIS, FRANCESCO INGROSSO, GABRIELE TESTA, Vincenzo |
Issue Date: | 2018 | Volume: | The Fourteenth Marcel Grossmann Meeting On Recent Developments in Theoretical and Experimental General Relativity, Astrophysics, and Relativistic Field Theories : Proceedings of the MG14 Meeting on General Relativity | Editors: | Bianchi, Massimo; Jantzen, Robert T.; Ruffini, Remo | First Page: | 1529 | Abstract: | We analyse archival XMM-Newton and Chandra observations of some dwarf MW satellites and characterized the X-ray source population by cross-correlating with available databases. We also investigate if intermediate-mass black holes are hosted in the center of these galaxies. In the most interesting case of UMI dwarf, we put an upper limit to the central compact object luminosity of ≃ 4 × 10<SUP>33</SUP> erg s<SUP>-1</SUP>. As the target correlates in position also with a radio source, we estimated a black hole mass of ≃ 32.0<SUB>-2.76</SUB><SUP>+2.54</SUP> × 10<SUP>6</SUP> M<SUB>☉</SUB>. | Acknowledgments: | We acknowledge the support by the INFN project TaSP. | Conference Name: | 14th Marcel Grossman Meeting on General Relativity | Conference Place: | Roma, University "La Sapienza" | Conference Date: | 12-18 July, 2015 | URI: | http://hdl.handle.net/20.500.12386/28256 | URL: | https://www.worldscientific.com/doi/abs/10.1142/9789813226609_0140 | ISBN: | 978-981-3226-59-3 | DOI: | 10.1142/9789813226609_0140 | Bibcode ADS: | 2018mgm..conf.1529N | Fulltext: | open |
