New techniques for high-resolution imaging and high-precision wavefront sensing via masked-aperture interferometry
Nithyanandan Thyagarajan, Bojan Nikolic, Chris Carilli +2
Achieving high-angular-resolution imaging on subarcsecond scales is fundamentally limited by wavefront aberrations imparted by the propagation medium and by optical elements along…
Exploiting Non Redundant Aperture Interferometry as a Diagnostics Tool for Synchrotron Light Characterization
C. Carilli, U. Iriso, B. Nikolic +2
We recently introduced a novel interferometric method inspired by radio astronomy, utilizing a Non-Redundant Aperture (NRA) mask with self-calibration to fully characterize the two…
Capabilities and Limitations of Non-Redundant Aperture Interferometry for Beam Size Measurements
C. Carilli, U. Iriso, B. Nikolic +3
Non-Redundant Aperture Interferometry (NRAI) is a beam characterization technique developed at ALBA in collaboration with radio-astronomy institutes. It enables the single-acquisit…
Establishing a relationship between the cosmological 21 cm power spectrum and interferometric closure phases
Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan
Measurements of the cosmic 21 cm signal need to achieve a high dynamic range to isolate it from bright foreground emissions. Calibration inaccuracies can compromise the spectral fi…
First Results from HERA Phase II
The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83
We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…
A New Method for Aperture Masking Interferometric Imaging: Demonstration with the JWST
Christopher Carilli, Bojan Nikolic, Laura Torino +2
We present a new method for aperture masking interferometric (AMI) imaging at near-IR wavelengths using radio astronomical techniques. The method starts with derivation of interfer…
