Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
- S. Smartt, T.-W. Chen, O. Yaron
- PhysicsNature
- 16 October 2017
Observations and physical modelling of a rapidly fading electromagnetic transient in the galaxy NGC 4993, which is spatially coincident with GW170817, indicate that neutron-star mergers produce gravitational waves and radioactively powered kilonovae, and are a nucleosynthetic source of the r-process elements.
Bolometric light curves and explosion parameters of 38 stripped-envelope core-collapse supernovae

- Physics
- 13 June 2014
Literature data are collated for 38 stripped-envelope core-collapse supernovae (SE SNe; i.e. SNe IIb, Ib, Ic and Ic-BL) that have good light curve coverage in more than one optical band. Using…

- 26 October 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced…
SUPER-LUMINOUS TYPE Ic SUPERNOVAE: CATCHING A MAGNETAR BY THE TAIL

- 11 April 2013
We report extensive observational data for five of the lowest redshift Super-Luminous Type Ic Supernovae (SL-SNe Ic) discovered to date, namely, PTF10hgi, SN2011ke, PTF11rks, SN2011kf, and SN2012il.…
LOCALIZATION AND BROADBAND FOLLOW-UP OF THE GRAVITATIONAL-WAVE TRANSIENT GW150914

- 26 February 2016
A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially…
A radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li

- PhysicsScience
- 27 November 2015
Radio follow-up observations of known thermal stellar tidal disruption flares (TDFs) are monitored and a detection of variable radio emission from a thermal TDF, which is interpreted as originating from a newly launched jet, suggests that all TDFs could be accompanied by a jet.
On the diversity of superluminous supernovae: ejected mass as the dominant factor
- M. Nicholl, S. Smartt, F. Yuan
- Physics
- 11 March 2015
We assemble a sample of 24 hydrogen-poor superluminous supernovae (SLSNe). Parameterizing the light-curve shape through rise and decline time-scales shows that the two are highly correlated.…
ULTRA-BRIGHT OPTICAL TRANSIENTS ARE LINKED WITH TYPE Ic SUPERNOVAE
- A. Pastorello, S. Smartt, U. F. Station
- Physics
- 16 August 2010
Recent searches by unbiased, wide-field surveys have uncovered a group of extremely luminous optical transients. The initial discoveries of SN 2005ap by the Texas Supernova Search and SCP-06F6 in a…
THE TYPE IIb SUPERNOVA 2011dh FROM A SUPERGIANT PROGENITOR
- M. Bersten, O. Benvenuto, L. Tomasella
- Physics
- 25 July 2012
A set of hydrodynamical models based on stellar evolutionary progenitors is used to study the nature of SN 2011dh. Our modeling suggests that a large progenitor star—with R ∼ 200 R☉—is needed to…
