“…The more luminous and relatively low dispersion measure sample of these ASKAP FRBs complements the distant events found in narrow-field and more sensitive surveys, e.g. Bhandari et al (2018); Keane et al (2018). These investigations of the brighter and closer FRB population are crucial in understanding the energetics of their radio emission.…”

We have conducted a search for bright repeating Fast Radio Bursts in our nearby Universe with the Australian Square Kilometer Array Pathfinder (ASKAP) in singledish mode. We used eight ASKAP 12-m dishes, each equipped with a Chequerboard Phased Array Feed forming 36 beams on the sky, to survey ∼30,000 deg 2 of the southern sky (−90 • < δ < +30 • ) in 158 antenna days. The fluence limit of the survey is 22 Jy ms. We report the detection of FRB 180515 in our survey. We found no repeating FRBs in a total mean observation of 3 hrs per pointing divided into one hour intervals, which were separated in time ranging between a day to a month. Using our non-detection, we exclude the presence of a repeating FRB similar to FRB 121102 closer than z = 0.004 in the survey area -a volume of at least 9.4 × 10 4 Mpc 3 -at 95% confidence.

“…With these and other modifications, it is likely that reprocessing of the HTRU-S LowLat survey will continue to yield new results for many years to come. Even with the ongoing Survey for Pulsars and Extragalactic Radio Bursts (SUPERB; Keane et al 2018) and the advent of the next generation of pulsar surveys which will be enabled by telescopes such as MeerKAT, FAST and the SKA, the steady production of new pulsar discoveries and other key scientific results from the multiple reprocessings of the PMPS (see e.g. Keane et al 2010;Eatough et al 2010Eatough et al , 2013 clearly demonstrates the value in reprocessing legacy surveys with a variety of search techniques.…”

We present the results of processing an additional 44 % of the High Time Resolution Universe South Low Latitude (HTRU-S LowLat) pulsar survey, the most sensitive blind pulsar survey of the southern Galactic plane to date. Our partially-coherent segmented acceleration search pipeline is designed to enable the discovery of pulsars in short, highly-accelerated orbits, while our 72-min integration lengths will allow us to discover pulsars at the lower end of the pulsar luminosity distribution. We report the discovery of 40 pulsars, including three millisecond pulsar-white dwarf binary systems (PSRs J1537−5312, J1547−5709 and J1618−4624), a black-widow binary system (PSR J1745−23) and a candidate black-widow binary system (PSR J1727−2951), a glitching pulsar (PSR J1706−4434), an eclipsing binary pulsar with a 1.5-yr orbital period (PSR J1653−45), and a pair of long spin-period binary pulsars which display either nulling or intermittent behaviour (PSRs J1812−15 and J1831−04). We show that the total population of 100 pulsars discovered in the HTRU-S LowLat survey to date represents both an older and lower-luminosity population, and indicates that we have yet to reach the bottom of the luminosity distribution function. We present evaluations of the performance of our search technique and of the overall yield of the survey, considering the 94 % of the survey which we have processed to date. We show that our pulsar yield falls below earlier predictions by approximately 25 % (especially in the case of millisecond pulsars), and discuss explanations for this discrepancy as well as future adaptations in RFI mitigation and searching techniques which may address these shortfalls.

“…Parkes -as part of the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB) (Keane et al 2018), we explored the data acquired using the 21-cm multibeam receiver (Staveley-Smith et al 1996) deployed on the Parkes radio telescope. The FWHM of each of the 13 beams is ∼ 14 arcmin, with an areal ∼ 2σ 13-beam coverage of ∼ 3 deg 2 .…”

Searches for optical transients are usually performed with a cadence of days to weeks, optimised for supernova discovery. The optical fast transient sky is still largely unexplored, with only a few surveys to date having placed meaningful constraints on the detection of extragalactic transients evolving at sub-hour timescales. Here, we present the results of deep searches for dim, minute-timescale extragalactic fast transients using the Dark Energy Camera, a core facility of our all-wavelength and all-messenger Deeper, Wider, Faster programme. We used continuous 20 s exposures to systematically probe timescales down to 1.17 minutes at magnitude limits g > 23 (AB), detecting hundreds of transient and variable sources. Nine candidates passed our strict criteria on duration and non-stellarity, all of which could be classified as flare stars based on deep multi-band imaging. Searches for fast radio burst and gamma-ray counterparts during simultaneous multi-facility observations yielded no counterparts to the optical transients. Also, no long-term variability was detected with pre-imaging and follow-up observations using the SkyMapper optical telescope. We place upper limits for minute-timescale fast optical transient rates for a range of depths and timescales. Finally, we demonstrate that optical g-band light curve behaviour alone cannot discriminate between confirmed extragalactic fast transients such as prompt GRB flashes and Galactic stellar flares.
