Search for the Epoch of Reionisation with HERA: Upper Limits on the Closure Phase Delay Power Spectrum

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan, Chris L. Carilli, Gianni Bernardi | Summary: Radio interferometers aiming to measure the power spectrum of the redshifted 21 cm line during the Epoch of Reionisation (EoR) need to achieve an unprecedented dynamic range to separate the weak signal […]

Improved noise performance from the next-generation buried-channel p-Mosfet SiSeROs

Kavli Affiliate: Gregory Prigozhin | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Matthew Kaplan, Peter Orel, Kevan Donlon | Summary: The Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors. Developed at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with a depleted […]

Emergent axion response in multilayered metamaterials

Kavli Affiliate: Frank Wilczek | First 5 Authors: Leon Shaposhnikov, Maxim Mazanov, Daniel A. Bobylev, Frank Wilczek, Maxim A. Gorlach | Summary: We consider the design of metamaterials whose behavior embodies the equations of axion electrodynamics. We derive an effective medium description of an assembly of magneto-optical layers with out-of-plane magnetization analytically and show how […]

Validating AU Microscopii d with Transit Timing Variations

Kavli Affiliate: Avi Shporer | First 5 Authors: Justin M. Wittrock, Peter Plavchan, Bryson L. Cale, Thomas Barclay, Mathis R. Ludwig | Summary: AU Mic is a young (22 Myr) nearby exoplanetary system that exhibits excess TTVs that cannot be accounted for by the two known transiting planets nor stellar activity. We present the statistical […]

Searching for Gravitational-Wave Counterparts using the Transiting Exoplanet Survey Satellite

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Geoffrey Mo, Rahul Jayaraman, Michael Fausnaugh, Erik Katsavounidis, George R. Ricker | Summary: In 2017, the LIGO and Virgo gravitational wave (GW) detectors, in conjunction with electromagnetic (EM) astronomers, observed the first GW multi-messenger astrophysical event, the binary neutron star (BNS) merger GW170817. This marked the beginning […]
