Role of Gaseous Disk in the Formation of the Spiral Structure of the Milky Way Galaxy

open access: yesOpen Astronomy, 2016
We use observational gaseous and stellar density distributions in the disk of the Milky Way (MW) galaxy together with the disk rotation curve and measured disk velocity dispersion to build collisionless and combined collisionless-gaseous equilibrium ...

The Merger Rate of Extremely Low Mass White Dwarf Binaries: Links to the Formation of AM CVn Stars and Underluminous Supernovae

open access: yes, 2010
We study a complete, colour-selected sample of double-degenerate binary systems containing extremely low mass (ELM) 3% of AM CVn stars. More importantly, the ELM WD systems that may detonate merge at a rate comparable to the estimated rate of ...

Disk Galaxy Evolution: From the Milky Way to High-Redshift Disks [PDF]

open access: yesAstrophysics and Space Science, 2003
We develop a detailed model of the Milky Way (a ``prototypical'' disk galaxy) and extend it to other disks with the help of some simple scaling relations, obtained in the framework of Cold Dark Matter models. This phenomenological (``hybrid'') approach to the study of disk galaxy evolution allows us to reproduce successfully a large number of observed ...

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

LZTS2 Negatively Regulates Centrosomal CEP135 Levels and Microtubule Nucleation

open access: yesCytoskeleton, EarlyView.
ABSTRACT The microtubule cytoskeleton is a fundamental functional component of the cell. In vertebrate proliferating cells, centrosomes are the primary microtubule organizing center (MTOC), and their dysregulation has been linked to genomic instability and cancer.

A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Microlensing Events in Five Years of Photometry from the Zwicky Transient Facility

open access: yesThe Astrophysical Journal
Microlensing has a unique advantage for detecting dark objects in the Milky Way, such as free-floating planets, neutron stars, and stellar-mass black holes.

The ESO-Max Planck photometric and spectroscopic survey in the south: EMPhaSSiS

open access: yesEPJ Web of Conferences, 2012
EMPhaSSiS is a photometric and spectroscopic survey of the disk of the Milky Way. The survey covers 33 fields in the 3rd quadrant of the Milky Way and probes every ten degrees in Galactic Longitude between l = 180∘ - 280∘ and at Galactic Latitudes of b =

Lipid Oxidation of Fish Oil‐in‐Water Pickering Emulsions Stabilized With Protein‐Based Janus Particles

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
ABSTRACT Pickering emulsions stabilized with solid particles have a significant advantage over conventional emulsions due to their high coalescence stability. However, their chemical stability, especially in fish oil‐in‐water Pickering emulsions, needs improvement.
