ePESSTO, the extended Public ESO Spectroscopic Survey for Transient Objects
(see Smartt et al. 2015, A&A, 579, 40; http://www.pessto.org ), reports the following
spectroscopic observation of the new X-ray source XMMSL2 J140446.9-251135 in the galaxy
2MASX 14044671-2511433 (ATel #11394).
The observation was performed on the ESO New Technology Telescope
at La Silla on 2018 March 8, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution).
Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al.,
2008, A&A, 488, 383). Classification spectra and additional details can be obtained
from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.
Survey Name | IAU Name | RA (J2000) | Dec (J2000) | Disc. Date | Source | Disc. Mag. | z | Type | Phase | Notes
XMMSL2 J140446.9-251135 | - | 14 04 46.54 | -25 11 42.00 | 2018 02 15 | ATel #11394 | - | 0.043 | galaxy | - | (1)
(1) The spectrum is that of the stellar component of a galaxy; the redshift is obtained from the position of the H, K I, Mg I and Na I absorption lines. There is no spectroscopic evidence for features expected in a tidal disruption event.
