Emulating Global 21 cm Cosmology Observations from the Lunar Far Side to Achieve Quick and Reliable Physical Constraints
J. Dorigo Jones, J. O. Burns, D. Rapetti +3
Efforts are underway to measure the global 21 cm signal from neutral hydrogen, which is a powerful probe of the early universe, using NASA radio telescopes on the far side of the M…
Validating posteriors obtained by an emulator when jointly-fitting mock data of the global 21-cm signal and high-z galaxy UV luminosity function
J. Dorigo Jones, D. Rapetti, J. Mirocha +3
Although neural-network-based emulators enable efficient parameter estimation in 21-cm cosmology, the accuracy of such constraints is poorly understood. We employ nested sampling t…
Dynamical vs Supernova Acceleration of OB Stars in the Small Magellanic Cloud
M. S. Oey, J. Dorigo Jones, G. D. Phillips +3
We use the RIOTS4 sample of SMC field OB stars to determine the origin of massive runaways in this low-metallicity galaxy using Gaia proper motions, together with stellar masses ob…
Improving blazar redshift constraints with the edge of the Ly forest: 1ES 1553+113 and implications for observations of the WHIM
J. Dorigo Jones, S. D. Johnson, Sowgat Muzahid +6
Blazars are some of the brightest UV and X-ray sources in the sky and are valuable probes of the elusive warm-hot intergalactic medium (WHIM; K). However, man…
Runaway OB Stars in the Small Magellanic Cloud: Dynamical Versus Supernova Ejections
J. Dorigo Jones, M. S. Oey, K. Paggeot +2
Runaway OB stars are ejected from their parent clusters via two mechanisms, both involving multiple stars: the dynamical ejection scenario (DES) and the binary supernova scenario (…
MWA tied-array processing III: Microsecond time resolution via a polyphase synthesis filter
S. J. McSweeney, S. M. Ord, N. D. R. Bhat +5
A new high time resolution observing mode for the Murchison Widefield Array (MWA) is described, enabling full polarimetric observations with up to 30.72 MHz of bandwidth and a time…
