“…On the other hand, the origin of short bursts (durations 2 s) remains mysterious. Current studies suggest that short GRBs are likely related to compact-object mergers and thus they are one of the candidate sources of gravitational waves (see e.g., Eichler et al 1989;Nakar 2007;Berger 2014, and reference therein), one of which has recently been detected directly by LIGO (Abbott et al 2016). Moreover, GRBs are one of the few astrophysical objects that can be directly detected out to very high redshift (z  8) due to their extraordinary brightness, and thus they provide a valuable tool to study the early universe.…”

To date, the Burst Alert Telescope (BAT) onboard Swift has detected ∼1000 gamma-ray bursts (GRBs), of which ∼360 GRBs have redshift measurements, ranging from z=0.03 to z=9.38. We present the analyses of the BATdetected GRBs for the past ∼11 years up through GRB151027B. We report summaries of both the temporal and spectral analyses of the GRB characteristics using event data (i.e., data for each photon within approximately 250 s before and 950 s after the BAT trigger time), and discuss the instrumental sensitivity and selection effects of GRB detections. We also explore the GRB properties with redshift when possible. The result summaries and data products are available at http://swift.gsfc.nasa.gov/results/batgrbcat/index.html. In addition, we perform searches for GRB emissions before or after the event data using the BAT survey data. We estimate the false detection rate to be only one false detection in this sample. There are 15 ultra-long GRBs (∼2% of the BAT GRBs) in this search with confirmed emission beyond ∼1000 s of event data, and only two GRBs (GRB100316D and GRB101024A) with detections in the survey data prior to the starting of event data.

“…Accretion onto the black hole then powers a relativistic transient, a short-duration gamma-ray burst (GRB; Narayan et al 1992;Ruffert & Janka 1999;Aloy et al 2005;Rezzolla et al 2011;Berger et al 2013;Tanvir et al 2013;Berger 2014;Ruiz et al 2016), with a prompt gamma-ray emission duration of  2 s. One of the biggest uncertainties in this canonical picture is how long the NS remnant survives prior to collapse. This depends on the mass of the final remnant and the highly uncertain Equation of State (EOS) of dense nuclear matter Lasky et al 2014;Fryer et al 2015;Lawrence et al 2015).…”

“…Metzger & Bower (2014) pointed out that the radio brightness of this interaction would be significantly enhanced in the case of a supramassive or stable magnetar remnant, due to the additional energy imparted to the ejecta by the injected rotational energy, which can exceed that of the dynamical ejecta by three or four orders of magnitude. Since there is substantial observational evidence linking short GRBs to NS mergers Tanvir et al 2013;Berger 2014), radio observations following short GRBs offer an independent way to explore the existence of long-lived (supramassive or stable) magnetar remnants. Using radio observations of seven short GRBs on ∼1-3 year timescales, Metzger & Bower (2014) placed constraints on the circumburst density of 0.1-1 cm −3 , assuming an energy reservoir of 3×10 52 erg.…”

Radio Constraints on Long-Lived Magnetar Remnants in Short Gamma-Ray Bursts

The merger of a neutron star (NS) binary may result in the formation of a rapidly spinning magnetar. The magnetar can potentially survive for seconds or longer as a supramassive NS before collapsing to a black hole if, indeed, it collapses at all. During this process, a fraction of the magnetar's rotational energy of ∼10 53 erg is transferred via magnetic spin-down to the surrounding ejecta. The resulting interaction between the ejecta and the surrounding circumburst medium powers a year-long or greater synchrotron radio transient. We present a search for radio emission with the Very Large Array following nine short-duration gamma-ray bursts (GRBs) at rest-frame times of ≈1.3-7.6 yr after the bursts, focusing on those events that exhibit early-time excess X-ray emission that may signify the presence of magnetars. We place upper limits of 18-32 μJy on the 6.0 GHz radio emission, corresponding to spectral luminosities of (0.05-8.3)×10 39 erg s −1 . Comparing these limits to the predicted radio emission from a long-lived remnant and incorporating measurements of the circumburst densities from broadband modeling of short GRB afterglows, we rule out a stable magnetar with an energy of 10 53 erg for half of the events in our sample. A supramassive remnant that injects a lower rotational energy of 10 52 erg is ruled out for a single event, GRB 050724A. This study represents the deepest and most extensive search for long-term radio emission following short GRBs to date, and thus the most stringent limits placed on the physical properties of magnetars associated with short GRBs from radio observations.

“…The interaction between stars in binaries is responsible for producing a variety of transient phenomena in astrophysics, including, among others, type Ia supernovae (single degenerate: Whelan & Iben 1973;double degenerate: Webbink 1984 andTutukov 1984), gamma-ray bursts (e.g., Brown, Lee, & Moreno Mén-dez 2007;Moreno Méndez et al 2011;Berger 2014), ultraluminous x-ray sources (e.g. Rappaport, Podsiadlowski, & Pfahl 2005;Liu et al 2013), novae (Crawford & Kraft 1956;Darnley et al 2012), millisecond pulsars (Wijnands & van der Klis 1998), gravitational waves (Taylor & Weisberg 1982;Abbott et al 2016), and common envelopes (CE; Ivanova et al 2013), among others.…”

Common envelope (CE) is an important phase in the evolution of many binary systems. Giant star / compact object interaction in binaries plays an important role in highenergy phenomena as well as in the evolution of their environment. Material accreted onto the compact object may form a disk and power a jet. We study analytically and through numerical simulations the interaction between the jet and the CE. We determine the conditions under which accreting material quenches the jet or allows it to propagate successfully, in which case even the envelope may be ejected. Close to the stellar core of the companion the compact object accretes at a larger rate. A jet launched from this region needs a larger accretion-to-ejection efficiency to successfully propagate through the CE compared to a jet launched far from the stellar core, and is strongly deflected by the orbital motion. The energy deposited by the jet may be larger than the binding energy of the envelope. The jet can, thus, play a fundamental role in the CE evolution. We find that the energy dissipation of the jet into the CE may stop accretion onto the disk. We expect the jet to be intermittent, unless the energy deposited is large enough to lead to the unbinding of the outer layers of the CE. Given that the energy and duration of the jet are similar to those of ultra-long GRBs, we suggest this as a new channel to produce these events.
