Revisiting EBL Constraints from Gamma-Ray Observations: A Critical Assessment and Methodological Improvements

K. Abe, S. Abe, J. Abhir +185

The extragalactic background light (EBL), ranging from the infrared to the ultraviolet bands, is the second most intense photon field in the universe, surpassed only by the cosmic…

Two stellar clocks, one history: a Gaia colour-magnitude-diagram reconstruction of the solar-neighbourhood star-formation history tested against white dwarfs

Michele Cignoni, Pier Giorgio Prada Moroni, Martina Gabbanini +2

The solar-neighbourhood star-formation history (SFH) can be constrained from the colour-magnitude diagram (CMD) of non-degenerate stars and tested independently with the white-dwar…

Detection of the distant quasar OP 313 with the first Large-Sized Telescope of CTAO

K. Abe, S. Abe, J. Abhir +412

In December 2023, the Large-Sized Telescope prototype (LST-1) detected for the first time VHE -ray emission from the FSRQ OP~313 becoming the furthest blazar ever observed at VH…

Element abundances of galactic RGB stars in the APO-K2 catalogue. Dissimilarity in the scaling with [/Fe]

G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1

We conducted an investigation on the chemical abundances of 4,316 stars in the red giant branch (RGB) phase from the recently released APO-K2 catalogue. Our aim was to characterize…

Constraints on Lorentz invariance violation from the extraordinary Mrk 421 flare of 2014 using a novel analysis method

MAGIC Collaboration, S. Abe, J. Abhir +214

The Lorentz Invariance Violation (LIV), a proposed consequence of certain quantum gravity (QG) scenarios, could instigate an energy-dependent group velocity for ultra-relativistic…

Constraining the helium-to-metal enrichment ratio from main sequence binary stars. Theoretical analysis of the accuracy and precision of the age and helium abundance estimates

G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1

We investigated the theoretical possibility of accurately determining the helium-to-metal enrichment ratio from precise observations of double lined eclipsing binary system…
