PBH-infused seesaw origin of matter and unique gravitational waves
Journal of High Energy Physics, 2023 The Standard Model, extended with three right-handed (RH) neutrinos, is the simplest model that can explain light neutrino masses, the baryon asymmetry of the Universe, and dark matter (DM).

The Origin of Cosmic Magnetic Fields
, 2000 In this talk, I review a number of particle-physics models that lead to the creation of magnetic fields in the early universe and address the complex problem of evolving such primordial magnetic fields into the fields observed today.

Journal of High Energy Physics, 2023 We discuss the dynamics of expanding bubble walls in the presence of massive dark photons whose mass changes as they cross the wall. For sufficiently thin walls, we show that there exists a transient kinematic regime characterized by a constant ...

Phase Transitions in the Early Universe [PDF]
, 2016 The physics of the 20th Century is governed by two pillars, Einstein's relativity principle and the quantum principle. At the beginning of the 21st Century, it becomes clear that there exist the smallest units of matter, such as electrons, neutrinos, and

Generation of Magnetic Fields in Cosmology [PDF]
, 2001 Mechanisms of generation of magnetic fields in the early universe which could seed the present-day large scale galactic magnetic fields, are briefly reviewed.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells
FEBS Letters, EarlyView.Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Thermalization effects on the dynamics of growing vacuum bubbles
Journal of High Energy PhysicsWe study the evolution of growing vacuum bubbles. The bubble walls interact with the surrounding fluid and may, consequently, reach a terminal velocity.

Gravitational waves-tomography of Low-Scale-Leptogenesis
Journal of High Energy Physics, 2022 A long-lived scalar field (Φ) which couples weakly to the right-handed (RH) neutrinos (N Ri ), generates small RH neutrino masses (M i ) in Low-Scale-Leptogenesis (LSL) mechanisms, despite having a large vacuum expectation value v Φ.

Gamma rays from ultracompact primordial dark matter minihalos
, 2009 Ultracompact minihalos have recently been proposed as a new class of dark matter structure. These minihalos would be produced by phase transitions in the early Universe or features in the inflaton potential, and constitute non-baryonic massive compact ...

Novel and unscrutinized immune entities of the zebrafish gut
FEBS Letters, EarlyView.Understudied cells of the zebrafish immune system include bona fide immune cells and epithelial (‐derived) cells with immune functions. Research focusing on zebrafish cells which demonstrate similarities to mammalian immune cell counterparts may help us understand the pathologies in which they are implicated. Currently available and advanced tools make
