The biophysical and compositional properties of human basement membranes

open access: yesThe FEBS Journal, Volume 291, Issue 3, Page 477-488, February 2024.
Basement membranes are exceptionally adaptable materials with both extremely stiff and highly elastic properties. This article highlights these features on a selection of human membranes and links them to compositional, biomechanical, and structural profiles down to a molecular level. The role of water in modulating these attributes is also scrutinized

Anisotropic Galactic Outflows and Enrichment of the Intergalactic Medium. I: Monte Carlo Simulations [PDF]

open access: yes, 2006
We have developed an analytical model to describe the evolution of anisotropic galactic outflows. With it, we investigate the impact of varying opening angle on galaxy formation and the evolution of the IGM. We have implemented this model in a Monte Carlo algorithm to simulate galaxy formation and outflows in a cosmological context.

The mean free path of hydrogen ionizing photons during the epoch of reionization [PDF]

open access: yes, 2017
We use the Aurora radiation-hydrodynamical simulations to study the mean free path (MFP) for hydrogen ionizing photons during the epoch of reionization. We directly measure the MFP by averaging the distance 1 Ry photons travel before reaching an optical depth of unity along random lines-of-sight.

On ALP scenarios and GRB 221009A [PDF]

open access: yesarXiv, 2022
The extraordinarily bright gamma-ray burst GRB 221009A was observed by a large number of observatories, from radio frequencies to gamma-rays. Of particular interest are the reported observations of photon-like air showers of very high energy: an 18 TeV event in LHAASO and a 251 TeV event at Carpet-2.

Anisotropic Outflows and Enrichment of the Intergalactic Medium [PDF]

open access: yesarXiv, 2006
We have developed an analytical model for the evolution of anisotropic galactic outflows. These outflows follow the path of least resistance, and thus travel preferentially into low-density regions, away from cosmological structures where galaxies form.

Relating the Interpolated Motion of Robots to Quantum Gravity and Intergalactic Travel

open access: yes, 2019
Interpolation is making the end of a robot arm move smoothly from one pose (position and orientation) to another ie programming it to move smoothly from A to B through a series of intermediate points. Linear interpolation does the job very nicely, but has the drawback that the motion is not totally smooth because of the accelerations. Point A initially

Runaway Stars and the Escape of Ionizing Radiation from High-Redshift Galaxies [PDF]

open access: yes, 2012
Approximately 30% of all massive stars in the Galaxy are runaways with velocities exceeding 30 km/s. Their high speeds allow them to travel ~0.1-1 kpc away from their birth place before they explode at the end of their several Myr lifetimes. At high redshift, when galaxies were much smaller than in the local universe, runaways could venture far from ...

Formation and spatial distribution of hypervelocity stars in AGN outflows [PDF]

open access: yes, 2017
We study star formation within outflows driven by active galactic nuclei (AGN) as a new source of hypervelocity stars (HVSs). Recent observations revealed active star formation inside a galactic outflow at a rate of $\sim 15\,M_{\odot}\,\rm yr^{-1}$. We verify that the shells swept up by an AGN outflow are capable of cooling and fragmentation into cold
