Cosmological constant, violation of cosmological isotropy and CMB
, 2009 We suggest that the solution to the cosmological vacuum energy puzzle does not require any new field beyond the standard model, but rather can be explained as a result of the interaction of the infrared sector of the effective theory of gravity with ...

, 2001 Recent observational advances have considerably improved the cosmological tests, adding to the lines of evidence, and showing that some issues under discussion just a few years ago may now be considered resolved or irrelevant.

Implications of the Neutron Star Merger GW170817 for Cosmological Scalar-Tensor Theories. [PDF]
Physical Review Letters, 2017 The LIGO and VIRGO Collaborations have recently announced the detection of gravitational waves from a neutron star-neutron star merger (GW170817) and the simultaneous measurement of an optical counterpart (the γ-ray burst GRB 170817A).

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

, 2004 We contrast the initial condition requirements of various contemporary cosmological models, including inflationary and bouncing cosmologies. Various proposals such as Hartle-Hawking's no boundary, or Tunnelling boundary conditions are assessed on grounds

The cosmological analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 The Effective Field Theory of Large-Scale Structure is a formalism that allows us to predict the clustering of Cosmological Large-Scale Structure in the mildly non-linear regime in an accurate and reliable way.

British Educational Research Journal, EarlyView.Abstract Considering the growing calls for decolonial approaches within the scope of Climate Change and Sustainability Education (CCSE), in this research we seek to understand the meanings which have been put into circulation through research narratives on Environmental Education (EE) concluded in Latin America, regarding Afro‐Amerindian knowledges ...

Journal of High Energy PhysicsGravitational-wave (GW) signals offer a unique window into the dynamics of the early universe. GWs may be generated by the topological defects produced in the early universe, which contain information on the symmetry of UV physics.

Thermodynamics of Bardeen black holes in restricted phase space
Physics Letters BIn this paper, we investigate the thermodynamics of Bardeen black holes within the framework of Restricted Phase Space (RPS) thermodynamics. Building upon the holographic interpretation of black hole thermodynamics, we derive key thermodynamic quantities,

The Astrophysical Journal Letters, 2023 The light from an extragalactic source at a distance d will arrive at detectors separated by 100 au at times that differ by as much as 120( d /100 Mpc) ^−1 nanoseconds because of the curvature of the wave front. At gigahertz frequencies, the arrival time
