Gravitational Waves and Time Domain Astronomy [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
The gravitational wave window onto the universe will open in roughly five years, when Advanced LIGO and Virgo achieve the first detections of high frequency gravitational waves, most likely coming from compact binary mergers. Electromagnetic follow-up of

A Data Science Platform to Enable Time-domain Astronomy

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

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

Gamma-Ray Astrophysics in the Time Domain

open access: yesGalaxies, 2019
The last few years have seen gamma-ray astronomy maturing and advancing in the field of time-domain astronomy, utilizing source variability on timescales over many orders of magnitudes, from a decade down to a few minutes and shorter, depending on the ...

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

Exploring the Time Domain With Synoptic Sky Surveys [PDF]

open access: yes, 2011
Synoptic sky surveys are becoming the largest data generators in astronomy, and they are opening a new research frontier, that touches essentially every field of astronomy.

Quasar Black Hole Mass Estimates in the Era of Time Domain Astronomy [PDF]

open access: yes, 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 ...

The Catalina Real-time Transient Survey [PDF]

open access: yes, 2011
The Catalina Real-time Transient Survey (CRTS) currently covers 33,000 deg^2 of the sky in search of transient astrophysical events, with time baselines ranging from 10 minutes to ~7 years.
