Author(s): Tylor Adkins et al. (POLARBEAR Collaboration) The Crab nebula is a calibration source for millimeter telescopes. The authors study the time variability of this calibration source with the Simons Array to put constraints on axion-like particles that would result in a time variation in the polarization. While they do not see any evidence of a signal, they are able to set competitive limits on these axion-like particles, which is similar...

Author(s): William R. Coulton et al. The authors use the relativistic thermal Sunyaev-Zeldovich effect in data from the Atacama Cosmology Telescope and Planck to measure the average electron temperature in galaxy-cluster stacks, thus paving the way for dramatic measurement improvements in upcoming survey data.

Author(s): Elisa G. M. Ferreira, Evan McDonough, Lennart Balkenhol, Renata Kallosh, Lloyd Knox, and Andrei Linde An apparent shift in the value of an important inflation parameter may be an artifact of differences between cosmological datasets. [Phys. Rev. D 113, 043524] Published Wed Feb 18, 2026

Author(s): Anirudh Deb and Shlomo S. Razamat The authors observe through technically challenging calculations a curious relation for a generalized Schur partition function, a special index that counts certain supersymmetric states in N=2 superconformal theories, they introduce. This generalization is parametrized by a continuous parameter, and for certain discrete parameters, one obtains partition functions of different theories, leading to the...

Author(s): Pawel Caputa, Bowen Chen, Ross W. McDonald, Joan Simón, and Benjamin Strittmatter As yet another manifestation of the holographic duality, it was proposed that the rate of growth of complexity of quantum states in a one-dimensional theory (Sachdev-Ye-Kitaev model) is proportional to the radial momentum of massive particles in the dual two-dimensional theory. By precisely matching the two sides, the authors show that this conjecture...

Author(s): Davide Pedrotti, Luis A. Escamilla, Valerio Marra, Leandros Perivolaropoulos, and Sunny Vagnozzi The authors demonstrate that, even if fiducial cosmology assumptions cause Baryon Acoustic Oscillation (BAO) measurements to bias low low-redshift acoustic angular scales, this cannot make post-recombination solutions to the Hubble tension plausible. Thus any such biases cannot be potential loopholes to this tension. [Phys. Rev. D 113...

Author(s): Afif Omar and Adam Ritz Despite its strong constraints, the consequences of big bang nucleosynthesis on near-GeV mass dark matter that decays to long-lived light hadrons have received little attention. With minimal model assumptions, the authors establish bounds on the parameter space of mass and branching fractions to hadrons superior to those of other indirect methods. [Phys. Rev.
