Synchronize your chrono-brane: testing a variable brane tension model with strong gravitational lensing

European Physical Journal C: Particles and Fields
Brane world models have shown to be promising to understand the late cosmic acceleration, in particular because such acceleration can be naturally derived, mimicking the dark energy behaviour just with a five dimensional geometry.

HAWC Detection of a TeV Halo Candidate Surrounding a Radio-quiet Pulsar

The Astrophysical Journal Letters, 2023
Extended very-high-energy (VHE; 0.1–100 TeV) γ -ray emission has been observed around several middle-aged pulsars and referred to as “TeV halos.” Their formation mechanism remains under debate. It is also unknown whether they are ubiquitous or related to

Detection of infalling hydrogen in transfer between the interacting galaxies NGC 5426 and NGC 5427

, 2011
Using velocity tagging we have detected hydrogen from NGC 5426 falling onto its interacting partner NGC 5427. Our observations, with the GHaFaS Fabry-Perot spectrometer, produced maps of the two galaxies in Halpha surface brightness and radial velocity ...
