Direct Far-Infrared Metal Abundances (FIRA) I: M101
C. Lamarche, J. D. Smith, K. Kreckel +12
Accurately determining gas-phase metal-abundances within galaxies is critical as metals strongly affect the physics of the interstellar medium (ISM). To date, the vast majority of…
Epoch of Reionization Power Spectrum Limits from Murchison Widefield Array Data Targeted at EoR1 Field
M. Rahimi, B. Pindor, J. L. B. Line +28
Current attempts to measure the 21cm Power Spectrum of neutral hydrogen during the Epoch of Reionization are limited by systematics which produce measured upper limits above both t…
Automated Detection of Antenna Malfunctions in Large-N Interferometers: A Case Study with the Hydrogen Epoch of Reionization Array
Dara Storer, Joshua S. Dillon, Daniel C. Jacobs +75
We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outlier…
First Results from HERA Phase I: Upper Limits on the Epoch of Reionization 21 cm Power Spectrum
The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +74
We report upper-limits on the Epoch of Reionization (EoR) 21 cm power spectrum at redshifts 7.9 and 10.4 with 18 nights of data ( hours of integration) from Phase I of the…
HERA Phase I Limits on the Cosmic 21-cm Signal: Constraints on Astrophysics and Cosmology During the Epoch of Reionization
The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +81
Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment's first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10.…
A new MWA limit on the 21 cm Power Spectrum at Redshifts 13 17
S. Yoshiura, B. Pindor, J. L. B. Line +29
Observations in the lowest MWA band between MHz have the potential to constrain the distribution of neutral hydrogen in the intergalactic medium at redshift .…
