Titolo: | XMM-Newton Slew Survey Observations of the Gravitational Wave Event GW150914 | Autori: | Troja, E. Read, A. M. Tiengo, A. SALVATERRA, Ruben |
Data pubblicazione: | 2016 | Rivista: | THE ASTROPHYSICAL JOURNAL | Numero: | 822 | Fascicolo: | 1 | Da pagina:: | L8 | Abstract: | The detection of the first gravitational wave (GW) transient GW150914 prompted an extensive campaign of follow-up observations at all wavelengths. Although no dedicated XMM-Newton observations have been performed, the satellite passed through the GW150914 error region during normal operations. Here we report the analysis of the data taken during these satellite slews performed two hours and two weeks after the GW event. Our data cover 1.1 and 4.8 deg<SUP>2</SUP> of the final GW localization region. No X-ray counterpart to GW150914 is found down to a sensitivity of 6 × 10<SUP>-13</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP> in the 0.2-2 keV band. Nevertheless, these observations show the great potential of XMM-Newton slew observations for searching for the electromagnetic counterparts of GW events. A series of adjacent slews performed in response to a GW trigger would take ≲1.5 days to cover most of the typical GW credible region. We discuss this scenario and its prospects for detecting the X-ray counterpart of future GW detections. | URI: | http://hdl.handle.net/20.500.12386/25009 | URL: | https://iopscience.iop.org/article/10.3847/2041-8205/822/1/L8 | ISSN: | 0004-637X | DOI: | 10.3847/2041-8205/822/1/L8 | Bibcode ADS: | 2016ApJ...822L...8T | Fulltext: | open |
