AT2019wxt: An ultra-stripped supernova candidate discovered in electromagnetic follow-up of a gravitational wave trigger
Hinna Shivkumar, Amruta D. Jaodand, Arvind Balasubramanian +13
We present optical, radio and X-ray observations of a rapidly-evolving transient AT2019wxt (PS19hgw), discovered during the search for an electromagnetic (EM) counterpart to the gr…
Transient Simulations for Radio Surveys
Sarah I Chastain, Alexander J van der Horst, Dario Carbone
Several new radio facilities have a field of view and sensitivity well suited for transient searches. This makes it more important than ever to accurately determine transient rates…
The Panchromatic Afterglow of GW170817: The full uniform dataset, modeling, comparison with previous results and implications
Sphesihle Makhathini, Kunal P. Mooley, Murray Brightman +35
We present the full panchromatic afterglow light curve data of GW170817, including new radio data as well as archival optical and X-ray data, between 0.5 and 940 days post-merger.…
LOFAR 144-MHz follow-up observations of GW170817
J. W. Broderick, T. W. Shimwell, K. Gourdji +66
We present low-radio-frequency follow-up observations of AT 2017gfo, the electromagnetic counterpart of GW170817, which was the first binary neutron star merger to be detected by A…
An optimized radio follow-up strategy for stripped-envelope core-collapse supernovae
Dario Carbone, Alessandra Corsi
Several on-going or planned synoptic optical surveys are offering or will soon be offering an unprecedented opportunity for discovering larger samples of the rarest types of stripp…
Constraining the duty cycle of transient low-mass X-ray binaries through simulations
Dario Carbone, Rudy Wijnands
We performed simulations of a large number of so-called very faint X-ray transient sources from surveys obtained using the X-ray telescope aboard the Neil Gehrels \emph{Swift} Obse…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
An upper-limit on the linear polarization fraction of the GW170817 radio continuum
Alessandra Corsi, Gregg W. Hallinan, Davide Lazzati +8
We present late-time radio observations of GW170817, the first binary neutron star merger discovered through gravitational waves by the advanced LIGO and Virgo detectors. Our obser…
LOFAR 150-MHz observations of SS 433 and W 50
J. W. Broderick, R. P. Fender, J. C. A. Miller-Jones +28
We present LOFAR high-band data over the frequency range 115-189 MHz for the X-ray binary SS 433, obtained in an observing campaign from 2013 February - 2014 May. Our results inclu…
Optimized Radio Follow Up of Binary Neutron-Star Mergers
Dario Carbone, Alessandra Corsi
Motivated by the recent discovery of the binary neutron-star (BNS) merger GW170817, we determine the optimal observational setup for detecting and characterizing radio counterparts…
Calculating transient rates from surveys
Dario Carbone, Alexander J. van der Horst, Ralph A. M. J. Wijers +1
We have developed a method to determine the transient surface density and transient rate for any given survey, using Monte-Carlo simulations. This method allows us to determine the…
A large light-mass component of cosmic rays at 10^{17} - 10^{17.5} eV from radio observations
S. Buitink, A. Corstanje, H. Falcke +101
Cosmic rays are the highest energy particles found in nature. Measurements of the mass composition of cosmic rays between 10^{17} eV and 10^{18} eV are essential to understand whet…
Low-radio-frequency eclipses of the redback pulsar J2215+5135 observed in the image plane with LOFAR
J. W. Broderick, R. P. Fender, R. P. Breton +30
The eclipses of certain types of binary millisecond pulsars (i.e. `black widows' and `redbacks') are often studied using high-time-resolution, `beamformed' radio observations. Howe…
Limits on Fast Radio Bursts and other transient sources at 182 MHz using the Murchison Widefield Array
A. Rowlinson, M. E. Bell, T. Murphy +33
We present a survey for transient and variable sources, on timescales from 28 seconds to 1 year, using the Murchison Widefield Array (MWA) at 182 MHz. Down to a detection thr…
