The Benefits and Harms of Transmitting Into Space

open access: yes, 2013
Deliberate and unintentional radio transmissions from Earth propagate into space. These transmissions could be detected by extraterrestrial watchers over interstellar distances.

A Time-domain Study of Repeat and Nonrepeat Fast Radio Bursts

open access: yesThe Astrophysical Journal
Fast radio bursts (FRBs) are extremely energetic radio transients, typically classified as repeat or nonrepeat, but their origins remain uncertain. In this work, we focus on the timing characteristics of the pulses in 536 FRBs observed by CHIME with ...

Varying Activity and the Burst Properties of FRB 20240114A Probed with GMRT Down to 300 MHz

open access: yesThe Astrophysical Journal
Repeating fast radio bursts (FRBs) can exhibit a wide range of burst repetition rates, from none to hundreds of bursts per hour. Here we report the detection and characteristics of 60 bursts from the recently discovered FRB 20240114A, observed with the ...

Ultrahigh-Energy Photons as a Probe of Nearby Transient Ultrahigh-Energy Cosmic-Ray Sources and Possible Lorentz-Invariance Violation

open access: yes, 2009
Detecting neutrinos and photons is crucial to identifying the sources of ultrahigh-energy cosmic rays (UHECRs), especially for transient sources. We focus on ultrahigh-energy gamma-ray emission from transient sources such as gamma-ray bursts, since >EeV ...

A new method for short-duration transient detection in radio images: searching for transient sources in MeerKAT data of NGC 5068

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT Transient surveys are a vital tool in exploring the dynamic Universe, with radio transients acting as beacons for explosive and highly energetic astrophysical phenomena. However, performing commensal transient surveys using radio imaging can require a significant amount of computing power, data storage, and time.

Radio sources in next-generation CMB surveys [PDF]

open access: yes, 2019
CMB surveys provide, for free, blindly selected samples of extragalactic radio sources at much higher frequencies than traditional radio surveys. Next-generation, ground-based CMB experiments with arcmin resolution at mm wavelengths will provide samples ...

A tale of two populations: Rotating Radio Transients and X-ray Dim Isolated Neutron Stars

open access: yes, 2006
We highlight similarities between recently discovered Rotating Radio Transients and X-ray Dim Isolated Neutron Stars. In particular, it is shown that X-ray Dim Isolated Neutron Stars have a birthrate comparable to that of Rotating Radio Transients.

Constraints on Fast Radio Burst Population from the First CHIME/FRB Catalog with the Hierarchical Bayesian Inference

open access: yesThe Astrophysical Journal
Fast radio bursts (FRBs) have emerged as one of the most dynamic areas of research in astronomy and cosmology. Despite increasing number of FRBs having been reported, the exact origin of FRBs remains elusive.

The RRAT Trap: Interferometric Localization of Radio Pulses from J0628+0909

open access: yes, 2012
We present the first blind interferometric detection and imaging of a millisecond radio transient with an observation of transient pulsar J0628+0909. We developed a special observing mode of the Karl G. Jansky Very Large Array (VLA) to produce correlated
