Fast Infrared Detector for Time-Domain Astronomy

open access: yesInstruments
Multi-messenger astronomy and time-domain astronomy are strongly linked even if they do not have the same objectives. Multi-messenger astronomy is an astrophysical observation approach born by the simultaneous, even if casual, detection of a few events ...

A Survey of Big Data Archives in Time-Domain Astronomy

open access: yesApplied Sciences, 2022
The rise of big data has resulted in the proliferation of numerous heterogeneous data stores. Even though multiple models are used for integrating these data, combining such huge amounts of data into a single model remains challenging. There is a need in

A Data Science Platform to Enable Time-domain Astronomy [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2023
SkyPortal is an open-source software package designed to discover interesting transients efficiently, manage follow-up, perform characterization, and visualize the results. By enabling fast access to archival and catalog data, crossmatching heterogeneous

Autoregressive Times Series Methods for Time Domain Astronomy [PDF]

open access: yesFrontiers in Physics, 2018
Celestial objects exhibit a wide range of variability in brightness at different wavebands. Surprisingly, the most common methods for characterizing time series in statistics—parametric autoregressive modeling—are rarely used to interpret astronomical ...

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

open access: yesThe 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?

open access: yesThe 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

open access: yesThe 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

AT 2023clx: The Faintest and Closest Optical Tidal Disruption Event Discovered in Nearby Star-forming Galaxy NGC 3799

open access: yesThe Astrophysical Journal Letters, 2023
We report the discovery of a faint optical tidal disruption event (TDE) in the nearby star-forming galaxy NGC 3799. Identification of the TDE is based on its position at the galaxy nucleus, a light curve declining as t ^−5/3 , a blue continuum with an ...
