On Under-determination in Cosmology [PDF]
, 2012 I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

Space and observers in cosmology [PDF]
Astronomy & Astrophysics, 2001 I provide a prescription to define space, at a given moment, for an arbitrary observer in an arbitrary (sufficiently regular) curved space-time. This prescription, based on synchronicity (simultaneity) arguments, defines a foliation of space-time, which corresponds to a family of canonically associated observers.

Modulated reheating and large non-gaussianity in string cosmology [PDF]
, 2012 A generic feature of the known string inflationary models is that the same physics that makes the inflaton lighter than the Hubble scale during inflation often also makes other scalars this light.

Observational constraints on soft dark energy and soft dark matter: Challenging ΛCDM cosmology
Nuclear Physics B, 2023 Soft cosmology is an extension of standard cosmology allowing for a scale-dependent equation-of-state (EoS) parameter in the dark sectors, which is one of the properties of soft materials in condensed-matter physics, that may arise either intrinsically ...

Highly Accreting Supermassive Black Holes as Eddington Standard Candles
Physical Sciences Forum, 2023 Supermassive black holes accreting matter at very high, perhaps even super-Eddington rates appear in the sky as a special class of luminous active galactic nuclei.

Low-Redshift Observational Constraints on Dark Energy Cosmologies [PDF]
Iranian Journal of Astronomy and Astrophysics, 2023 Applying the Markov chain Monte Carlo algorithm and using low-redshift observational data, we put cosmological constraints on dark energy cosmologies. Our main aim is to show the influence of each data sample on the procedure of constraining.

Proceedings of European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2019), 2020 Despite the title, I am afraid that I will not be able to really do justice to the broad topic I was given to review. But I will show the current striking level of precise consistency between the CMB and LSS data \textit{within the \LCDM\ theoretical framework} (with the acronyms CMB and LSS standing for Cosmic Microwave Background and Large Scale ...
