Tests of Loop Quantum Gravity from the Event Horizon Telescope Results of Sgr A

Misba Afrin, Sunny Vagnozzi, Sushant G. Ghosh

The Event Horizon Telescope (EHT) collaboration's image of the compact object at the galactic center is the first direct evidence of the supermassive black hole (BH) Sgr A. The…

The challenge of ruling out inflation via the primordial graviton background

Sunny Vagnozzi, Abraham Loeb

Recent debates around the testability of the inflationary paradigm raise the question of how to model-independently discriminate it from competing scenarios. We argue that a detect…

Updated neutrino mass constraints from galaxy clustering and CMB lensing-galaxy cross-correlation measurements

Isabelle Tanseri, Steffen Hagstotz, Sunny Vagnozzi +2

We revisit cosmological constraints on the sum of the neutrino masses from a combination of full-shape BOSS galaxy clustering [] data and measurements of the cross-cor…

Restoring cosmological concordance with early dark energy and massive neutrinos?

Alexander Reeves, Laura Herold, Sunny Vagnozzi +2

The early dark energy (EDE) solution to the Hubble tension comes at the cost of an increased clustering amplitude that has been argued to worsen the fit to galaxy clustering data.…

Note on fundamental physics tests from black hole imaging: Comment on "Hunting for extra dimensions in the shadow of Sagittarius A"

Sunny Vagnozzi, Luca Visinelli

Several works over the past years have discussed the possibility of testing fundamental physics using Very Long Baseline Interferometry horizon-scale black hole (BH) images, such a…

Horizon-scale tests of gravity theories and fundamental physics from the Event Horizon Telescope image of Sagittarius A

Sunny Vagnozzi, Rittick Roy, Yu-Dai Tsai +12

Horizon-scale images of black holes (BHs) and their shadows have opened an unprecedented window onto tests of gravity and fundamental physics in the strong-field regime. We conside…
