Time domain astronomy with the THESEUS satellite [PDF]

Experimental Astronomy, 2021
THESEUS is a medium size space mission of the European Space Agency, currently under evaluation for a possible launch in 2032. Its main objectives are to investigate the early Universe through the observation of gamma-ray bursts and to study the gravitational waves electromagnetic counterparts and neutrino events.

Tracking the Enigmatic Globular Cluster Ultracompact X-Ray Binary X1850–087: Extreme Radio Variability in the Hard State

The Astrophysical Journal, 2023
The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850–087, located in the globular cluster NGC 6712, is a persistent atoll-type X-ray source that has

Is the M81 Fast Radio Burst Host Globular Cluster Special?

The Astrophysical Journal Letters, 2023
We use multiband archival Hubble Space Telescope (HST) observations to measure the photometric and structural parameters of the M81 globular cluster (GC) that hosts the fast radio burst FRB 20200120E. Our best-fitting King model has an effective radius r

Evidence for Multiple Shocks from the γ-Ray Emission of RS Ophiuchi

The Astrophysical Journal, 2023
In 2021 August, the Fermi Large Area Telescope, H.E.S.S., and MAGIC detected GeV and TeV γ -ray emission from an outburst of recurrent nova RS Ophiuchi. This detection represents the first very high-energy γ -rays observed from a nova, and it opens a new

Coherent Time-domain Canceling of Interference for Radio Astronomy

Publications of the Astronomical Society of the Pacific, 2022
Abstract Radio astronomy is vulnerable to interference from a variety of anthropogenic sources. Among the many strategies for mitigation of this interference is coherent time-domain canceling (CTC), which ideally allows one to “look through” interference, as opposed to avoiding the interference or deleting the afflicted data.
