The cosmic web's Lyman- glow at ; hydrodynamic models, dust, and wide-field, narrow-band detection
Oleksii Sokoliuk, John K. Webb, Kenneth M. Lanzetta +12
The diffuse Lyman- glow of the cosmic web has long been predicted but has so far eluded direct detection over cosmologically significant volumes. We construct synthetic Lyman-$α…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Explaining JWST star formation history at by modifying CDM
Oleksii Sokoliuk
Recent cosmological observations indicate a discrepancy between the values of the Hubble constant derived from late and early universe probes. A further possible tension…
Holographic Boundary Conformal Field Theory within Horndeski Gravity
Fabiano F. Santos, Behnam Pourhassan, Emmanuel N. Saridakis +3
We investigate entanglement islands and the Page curve in the framework of Horndeski gravity on a Karch-Randall braneworld background. In particular, treating the holographic bound…
Early-Time Observations of SN 2023wrk: A Luminous Type Ia Supernova with Significant Unburned Carbon in the Outer Ejecta
Jialian Liu, Xiaofeng Wang, Cristina Andrade +44
We present extensive photometric and spectroscopic observations of the nearby Type Ia supernova (SN) 2023wrk at a distance of about 40 Mpc. The earliest detection of this SN can be…
AdS black hole thermodynamics and microstructures from gravitation
Oleksii Sokoliuk, Sneha Pradhan, Alexander Baransky +1
The significant properties and phase transition of charged Anti-de Sitter (AdS) black holes have been extensively studied in a variety of modified theories of gravity in the presen…

Tension in Torsion-based Modified Gravity
Sanjay Mandal, Oleksii Sokoliuk, Sai Swagat Mishra +1
The rising concern in the Hubble constant tension ( tension) of the cosmological models motivates the scientific community to search for alternative cosmological scenarios tha…
AdS/BCFT correspondence and Horndeski gravity in the presence of gauge fields: holographic paramagnetism/ferromagnetism phase transition
Fabiano F. Santos, Moisés Bravo-Gaete, Oleksii Sokoliuk +1
This paper presents a dual gravity model for a (2+1)-dimensional system with a limit on finite charge density and temperature, which will be used to study the properties of the hol…
Holographic complexity of braneworld in Horndeski gravity
