The NANOGrav 15-year data set: Search for Transverse Polarization Modes in the Gravitational-Wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +96

Recently we found compelling evidence for a gravitational wave background with Hellings and Downs (HD) correlations in our 15-year data set. These correlations describe gravitation…

How to Detect an Astrophysical Nanohertz Gravitational-Wave Background

Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93

Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…

Comparing recent PTA results on the nanohertz stochastic gravitational wave background

The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242

The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…

A Cryogenic Wideband (2.5-14 GHz) Receiver system for the Arecibo 12m Telescope

D. Anish Roshi, Phil Perillat, Felix Fernandez +5

In this paper we present details of the construction of a wideband, cryogenic receiver and its successful commissioning on the Arecibo 12m telescope. The cryogenic receiver works i…

The NANOGrav 15-year Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational Wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111

The NANOGrav 15-year data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gr…

Solar Radio Imaging at Arecibo: The Brightness Temperature and Magnetic Field of Active Regions

P. K. Manoharan, C. J. Salter, S. M. White +5

Strong solar magnetic fields are the energy source of intense flares and energetic coronal mass ejections of space weather importance. The key issue is the difficulty in predicting…
