New results concerning the curvature of the Universe
Maxim Khlopov, Maxim Krasnov, Jan Novák
One of the fundamental questions we ask in cosmology is what the spatial curvature of the universe is. Experimental observations show that the universe is very close to being spati…
Accelerating expansion and isotropic sky-hemisphere consistency in Pantheon+ supernovae: a revised analysis in the dark energy debate
Saibal Ray, Maxim Khlopov, Aritra Sanyal +2
We perform four independent decompositions of the deceleration parameter using 1564 Type Ia supernovae (SNe Ia) from the Pantheon+ catalogue: by redshift bin, sky hemisphere,…
Observationally Constrained Cosmological model in Gravity with parameterization
Vinod Kumar Bhardwaj, Maxim Khlopov, Maxim Krasnov +1
In the present work, we explore an observationally constrained cosmological model in the framework of gravity, where denotes the non-metricity scalar and…
Strong primordial inhomogeneities of axion-like field in Einstein-Gauss-Bonnet gravity
M. A. Krasnov, D. Z. Berkimbayev, A. Addazi +2
In this paper we consider complex scalar field with Mexican hat potential coupled with Gauss-Bonnet scalar resulting in restored U(1) symmetry at the stage of inflation, correspond…
Solar System and Atomic Clock Bounds on Locally Coupled Swampland Scalars
Suraj Gavhale, Maxim Khlopov, Oem Trivedi +1
We study how local measurements constrain light scalar fields that are relevant in late time cosmic acceleration and are often discussed in connection with swampland criteria. Star…
Machine Learning for Multi-messenger Probes of New Physics and Cosmology: A Review and Perspective
Andrea Addazi, Konstantin Belotsky, Vitaly Beylin +18
The multi-messenger exploration of dark matter and physics beyond the Standard Model has emerged as a central direction in modern astro-particle physics, particularly following the…
Proceedings to the 28th Workshop What Comes Beyond the Standard Models
Norma Susana Mankoč Borštnik, Holger Bech Nielsen, Maxim Yu. Khlopov +1
This year was 28th time that our series of workshops entitled "What Comes Beyond the Standard Models?" took place. The series started in 1998 with the idea of organising a workshop…
Chemical evolution of antimatter domains in early Universe
A. I. Dembitskaia, Stephane Weiss, M. Yu. Khlopov +1
According to modern physics, our Universe is baryon-asymmetric. That phenomenon can not be described in the frameworks of the Standard Model of particle physics. Globally, the Univ…
Particle production and Higgs reheating
Aarav Shah, Kanabar Jay, Maxim Khlopov +2
Reheating is essential for transforming the cold, vacuum dominated Universe at the end of inflation into the hot thermal bath required by the Standard Model. In many well motivated…
Inflation and Primordial Perturbations in Fractal Cosmology
Aarav Shah, Paulo Moniz, Maxim Khlopov +2
We study inflationary dynamics within the framework of fractal cosmology, where space is characterized by an effective non-integer dimension . In our work, fractal effects are s…
