Ultrawide-angle diffraction-limited 2D beam steering via hybrid integrated metasurface-photonic circuit
Zhiping He, Luigi Ranno, Padraic Burns +12
Two-dimensional (2D) wide field-of-view (FOV) beam steering is a key enabling capability for emerging free-space optical systems, including inter-satellite optical links, airborne…

Cosmological dynamics of interacting dark matter-dark energy in generalized Rastall gravity
Manuel Gonzalez-Espinoza, Ramón Herrera, Giovanni Otalora +2
In this work, we investigate late-time interacting cosmologies within the framework of generalized Rastall gravity, where the interaction arises naturally from the non-conservation…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
