Bistability of Exciton-Photon Microcavities in the Ultrastrong-Coupling Regime

Rashed Aljasmi, Hisham Sati, Hichem Eleuch

We investigate a coherently driven exciton--photon microcavity with Kerr nonlinearity in the ultrastrong-coupling regime. When the lower and upper polariton branches are well separ…

Gravitational Wave from Graviton Bremsstrahlung during Reheating

Basabendu Barman, Nicolás Bernal, Yong Xu +1

We revisit graviton production via Bremsstrahlung from the decay of the inflaton during inflationary reheating. Using two complementary computational techniques, we first show that…

RAD@home discovery of a bow-and-arrow radio galaxy tracing a ~560 kpc bow-shock structure in a multi-halo environment

Ananda Hota, Pratik Dabhade, Shubhrangshu Ghosh +9

We report the RAD@home citizen science discovery of a unique bow-and-arrow-shaped radio galaxy (BAARG; RAD J104501.6+352852, z = 0.159) identified in LoTSS DR2. The source exhibits…

Euclid: Quick Data Release (Q1) -- LensMC shear measurement catalogue for cluster lensing science

G. Congedo, M. Sereno, H. Miyatake +140

We present a LensMC lensing analysis of Euclid Quick Release 1 images that were made available in March 2025. We measured shapes, positions, weights, and other morphological parame…

Covariant Lie Derivatives and (Super-)Gravity

Grigorios Giotopoulos

The slightly subtle notion of covariant Lie derivatives of \textit{bundle-valued} differential forms is crucial in many applications in physics, notably in the computation of conse…

Towards inertial-mode helioseismology: Direct sensing of solar rotation at 75 deg latitude and 0.8 Rsun

Prithwitosh Dey, Laurent Gizon, Yuto Bekki

Solar internal rotation at high latitudes is poorly constrained by acoustic-mode helioseismology. Global inertial modes observed on the Sun are highly sensitive to solar differenti…
