The return of the spin period in DW Cnc and evidence of new high state outbursts
C. Duffy, G. Ramsay, D. Steeghs +16
DW Cnc is an intermediate polar which has previously been observed in both high and low states. Observations of the high state of DW Cnc have previously revealed a spin period at ~…
The Gravitational-wave Optical Transient Observer (GOTO): prototype performance and prospects for transient science
D. Steeghs, D. K. Galloway, K. Ackley +50
The Gravitational-wave Optical Transient Observer (GOTO) is an array of wide-field optical telescopes, designed to exploit new discoveries from the next generation of gravitational…
Searching for TeV gamma-ray emission from SGR\,1935+2154 during its 2020 X-ray and radio bursting phase
H. E. S. S. Collaboration, :, H. Abdalla +251
Magnetar hyperflares are the most plausible explanation for fast radio bursts (FRB) -- enigmatic powerful radio pulses with durations of several milliseconds and high brightness te…
Searching For Fermi GRB Optical Counterparts With The Prototype Gravitational-Wave Optical Transient Observer (GOTO)
Y. -L. Mong, K. Ackley, D. K. Galloway +45
The typical detection rate of gamma-ray burst (GRB) per day by the \emph{Fermi} Gamma-ray Burst Monitor (GBM) provides a valuable opportunity to further our understanding o…
Search for dark matter annihilation signals from the Galactic Center with the H.E.S.S. Inner Galaxy Survey
A. Montanari, E. Moulin, D. Malyshev
The presence of dark matter (DM) is suggested by a wealth of astrophysical and cosmological measurements. However, its underlying nature is yet unknown. Among the most promising ca…
Evidence of 100 TeV -ray emission from HESS J1702-420: A new PeVatron candidate
L. Giunti, B. Khelifi, K. Kosack +1
The identification of active PeVatrons, hadronic particle accelerators reaching the knee of the cosmic-ray spectrum (at the energy of few PeV), is crucial to understand the origin…
LMC N132D: A mature supernova remnant with a power-law gamma-ray spectrum extending beyond 8 TeV
H. E. S. S. Collaboration, :, H. Abdalla +233
We analyzed 252 hours of High Energy Stereoscopic System (H.E.S.S.) observations towards the supernova remnant (SNR) LMC N132D that were accumulated between December 2004 and March…
TeV emission of Galactic plane sources with HAWC and H.E.S.S
H. Abdalla, F. Aharonian, F. Ait Benkhali +318
The High Altitude Water Cherenkov (HAWC) observatory and the High Energy Stereoscopic System (H.E.S.S.) are two leading instruments in the ground-based very-high-energy gamma-ray d…
Search for dark matter annihilation signals from unidentified Fermi-LAT objects with H.E.S.S
H. E. S. S. Collaboration, H. Abdallah, F. Aharonian +226
Cosmological -body simulations show that Milky Way-sized galaxies harbor a population of unmerged dark matter subhalos. These subhalos could shine in gamma-rays and be eventuall…
Revealing x-ray and gamma ray temporal and spectral similarities in the GRB 190829A afterglow
H. E. S. S. Collaboration
Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events.…
Light curve classification with recurrent neural networks for GOTO: dealing with imbalanced data
U. F. Burhanudin, J. R. Maund, T. Killestein +42
The advent of wide-field sky surveys has led to the growth of transient and variable source discoveries. The data deluge produced by these surveys has necessitated the use of machi…
Processing GOTO data with the Rubin Observatory LSST Science Pipelines II: Forced Photometry and light curves
L. Makrygianni, J. Mullaney, V. Dhillon +45
We have adapted the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) Science Pipelines to process data from the Gravitational-Wave Optical Transient Observer (GOTO)…
Search for dark matter annihilation in the dwarf irregular galaxy WLM with H.E.S.S
H. E. S. S. Collaboration, H. Abdallah, R. Adam +232
We search for an indirect signal of dark matter through very high-energy gamma rays from the Wolf-Lundmark-Melotte (WLM) dwarf irregular galaxy. The pair annihilation of dark matte…
Transient-optimised real-bogus classification with Bayesian Convolutional Neural Networks -- sifting the GOTO candidate stream
T. L. Killestein, J. Lyman, D. Steeghs +45
Large-scale sky surveys have played a transformative role in our understanding of astrophysical transients, only made possible by increasingly powerful machine learning-based filte…
Evidence that short period AM CVn systems are diverse in outburst behaviour
C. Duffy, G. Ramsay, D. Steeghs +12
We present results of our analysis of up to 15 years of photometric data from eight AM CVn systems with orbital periods between 22.5 and 26.8 min. Our data has been collected from…
