Profile Analysis of the Multiwavelength 2.1-year Oscillations of PG 1553+113
P. Peñil, P. Peñil, N. Torres-Albà +8
We investigate the morphology of the oscillation profiles of the blazar PG~1553+113 in relation to its well-known 2.1 yr periodicity. We identify individual cycles in the …

Testing X-ray Periodicity and Long-Term Trend in PG 1553+113 via Targeted Swift-XRT Monitoring
P. Peñil, N. Torres-AlbÃ, L. Marcotulli +5
PG~1553+113 is the blazar with the most-significantly detected periodic patter in its multiwavelength (MWL) emission, making it one of the most promising candidates for hosting a s…

- cosmological model with new data samples of cosmological observations
Dorian Araya, Cristian Castillo, Genly Leon +3
We revisit a cosmological model where dark matter (DM) and dark energy (DE) follow barotropic equations of state, allowing deviations from the standard CDM framework (i.e. $w_{…
