Orbital Dynamics of Candidate Transitional Millisecond Pulsar 3FGL J1544.6-1125: An Unusually Face-on System [PDF]
, 2017 We present the orbital solution for the donor star of the candidate transitional millisecond pulsar (tMSP) 3FGL J1544.6-1125, currently observed as an accreting low-mass X-ray binary.

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.

Quasar Black Hole Mass Estimates in the Era of Time Domain Astronomy [PDF]
, 2013 We investigate the dependence of the normalization of the high-frequency part of the X-ray and optical power spectral densities (PSD) on black hole mass for a sample of 39 active galactic nuclei (AGN) with black hole masses estimated from reverberation ...

Trend filtering – I. A modern statistical tool for time-domain astronomy and astronomical spectroscopy [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The problem of denoising a 1D signal possessing varying degrees of smoothness is ubiquitous in time-domain astronomy and astronomical spectroscopy. For example, in the time domain, an astronomical object may exhibit a smoothly varying intensity that is

How Swift is redefining time domain astronomy
Journal of High Energy Astrophysics, 2015 NASA's Swift satellite has completed ten years of amazing discoveries in time domain astronomy. Its primary mission is to chase gamma-ray bursts (GRBs), but due to its scheduling flexibility it has subsequently become a prime discovery machine for new types of behavior.
