Rxte All-sky Monitor Localization of Sgr 1627–41
نویسنده
چکیده
The fourth unambiguously identified Soft Gamma Repeater (SGR), SGR 1627–41, was discovered with the BATSE instrument on 1998 June 15 (Kouveliotou et al. 1998). Interplanetary Network (IPN) measurements and BATSE data constrained the location of this new SGR to a 6 segment of a narrow (19) annulus (Hurley et al. 1999a; Woods et al. 1998). We present two bursts from this source observed by the All-Sky Monitor (ASM) on RXTE. We use the ASM data to further constrain the source location to a 5 long segment of the BATSE/IPN error box. The ASM/IPN error box lies within 0.3 of the supernova remnant (SNR) G337.0–0.1. The probability that a SNR would fall so close to the error box purely by chance is ∼ 5%. Subject headings: gamma rays: bursts – X-rays: bursts – stars: neutron

متن کاملPrecise Localization of the Soft Gamma Repeater SGR 1627−41 and the Anomalous X-ray Pulsar AXP 1E1841−045 with Chandra
We present precise localizations of AXP 1E1841−045 and SGR 1627−41 with Chandra. We obtained new infrared observations of SGR 1627−41 and reanalyzed archival observations of AXP 1E1841−045 in order to refine their positions and search for infrared counterparts. A faint source is detected inside the error circle of AXP 1E1841−045. In the case of SGR 1627−41, several sources are located within th...
متن کاملXMM-Newton observations of the Soft Gamma Ray Repeater SGR 1627–41 in a low luminosity state
The sky region containing the soft gamma-ray repeater SGR 1627–41 has been observed three times with XMM-Newton in February and September 2004. SGR 1627–41 has been detected with an absorbed flux of ∼9×10 erg cm s (2-10 keV). For a distance of 11 kpc, this corresponds to a luminosity of ∼3×10 erg s, the smallest ever observed for a Soft Gamma Repeater and possibly related to the long period of ...

The sky region containing the soft gamma-ray repeater SGR 1627–41 and the hard X-ray transient IGR J16358–4726 has been observed with XMM-Newton in September 2004. SGR 1627–41 has been detected with an absorbed flux of ∼9×10 erg cm s (2-10 keV), slightly smaller than that seen with Chandra in 2001-2003. For a distance of 11 kpc, this corresponds to a luminosity of ∼3×10 erg s, the smallest ever...
متن کاملX-ray Transients Monitored by the All- Sky Monitor on Rxte: a Tabulation
We present a tabulation of 46 transient x-ray sources monitored with the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE). They fall into four broad categories: short (∼ 1 d), intermediate, and long (> 500 d) duration of outbursts, and long period binary systems that flare up at periastron (e.g., Be systems). The mixture of outburst/quiescent cycles and low-level persistent emiss...
