Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853
Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…
Glueball dark matter, precisely
Pierluca Carenza, Tassia Ferreira, Roman Pasechnik +1
We delve deeper into the potential composition of dark matter as stable scalar glueballs from a confining dark gauge theory, focusing on . To predict the relic…
The N5K Challenge: Non-Limber Integration for LSST Cosmology
C. D. Leonard, T. Ferreira, X. Fang +9
The rapidly increasing statistical power of cosmological imaging surveys requires us to reassess the regime of validity for various approximations that accelerate the calculation o…
A fast and reliable method for the comparison of covariance matrices
Tassia Ferreira, Valerio Marra
Covariance matrices are important tools for obtaining reliable parameter constraints. Advancements in cosmological surveys lead to larger data vectors and, consequently, increasing…
Data Compression and Covariance Matrix Inspection: Cosmic Shear
Tassia Ferreira, Tianqing Zhang, Nianyi Chen +1
Covariance matrices are among the most difficult pieces of end-to-end cosmological analyses. In principle, for two-point functions, each component involves a four-point function, a…
Bayesian Comparison of Interacting Scenarios
Antonella Cid, Beethoven Santos, Cassio Pigozzo +2
We perform a Bayesian model selection analysis for different classes of phenomenological coupled scenarios of dark matter and dark energy with linear and non-linear interacting ter…
Interaction in the dark sector: a Bayesian analysis with latest observations
T. Ferreira, C. Pigozzo, S. Carneiro +1
By combining cosmological probes at low, intermediate and high redshifts, we investigate the observational viability of a class of models with interaction in the dark sector. We pe…
