WALLABY Pilot Survey: H i in the Host Galaxy of a Fast Radio Burst
The Astrophysical Journal, 2023 We report on the commensal ASKAP detection of a fast radio burst (FRB), FRB 20211127I, and the detection of neutral hydrogen (H i ) emission in the FRB host galaxy, WALLABY J131913–185018 (hereafter W13–18).

Properties of Specialist Fibres and Bragg Gratings for Optical Fiber Sensors
Journal of Sensors, Volume 2009, Issue 1, 2009., 2009 The advent of optical fibres based on air holes running along their entirety opens up new directions in addressing various properties relevant to sensing, including the temperature/strain challenge of optical fibre sensors. This paper looks at the measurement challenges associated with temperature and strain, examines the potentially unique ...

The Astrophysical Journal, 2023 Current methods of identifying the ionizing source of nebular emission in galaxies are well defined for the era of single-fiber spectroscopy, but still struggle to differentiate the complex and overlapping ionization sources in some galaxies.

TOI-1859b: A 64 Day Warm Jupiter on an Eccentric and Misaligned Orbit
The Astrophysical Journal Letters, 2023 Warm Jupiters are close-in giant planets with relatively large planet–star separations (i.e., 10 < a / R _⋆ < 100). Given their weak tidal interactions with their host stars, measurements of stellar obliquity may be used to probe the initial obliquity ...

Streams on FIRE: Populations of Detectable Stellar Streams in the Milky Way and FIRE
The Astrophysical Journal, 2023 We present the first detailed comparison of populations of dwarf galaxy stellar streams in cosmological simulations and the Milky Way. In particular, we compare streams identified around 13 Milky Way analogs in the FIRE-2 simulations to streams observed ...

The Role of Binarity and Stellar Rotation in the Split Main Sequence of NGC 2422
The Astrophysical Journal, 2022 In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (∼600 Myr to 2 Gyr old) star clusters, some younger clusters even exhibit split main sequences (MSs).
