The composition of the protosolar disk and the formation conditions for comets [PDF]

, 2015
Conditions in the protosolar nebula have left their mark in the composition of cometary volatiles, thought to be some of the most pristine material in the solar system.

Nebula/DSCR1 upregulation delays neurodegeneration and protects against APP-induced axonal transport defects by restoring calcineurin and GSK-3β signaling. [PDF]

PLoS Genetics, 2013
Post-mortem brains from Down syndrome (DS) and Alzheimer's disease (AD) patients show an upregulation of the Down syndrome critical region 1 protein (DSCR1), but its contribution to AD is not known.

Discovery of an Enormous Lyα Nebula in a Massive Galaxy Overdensity at z = 2.3 [PDF]

, 2016
Enormous Lyα nebulae (ELANe), unique tracers of galaxy density peaks, are predicted to lie at the nodes and intersections of cosmic filamentary structures.

Optical and infrared properties of V1647 Orionis during the 2003-2006 outburst. I The reflection nebula

, 2007
Aims: The recent outburst of the young eruptive star V1647 Orionis has produced a spectacular appearance of a new reflection nebula in Orion (McNeil's nebula). We present an optical/near infrared investigation of McNeil's nebula.

GEMINGA’S PUZZLING PULSAR WIND NEBULA [PDF]

, 2016
We report on six new Chandra observations of the Geminga pulsar wind nebula (PWN). The PWN consists of three distinct elongated structures—two ≈ 0.2 d 250 pc long lateral tails and a segmented axial tail of ≈ 0.05 d 250 pc length, where d 250 = d / ( 250

Two-zone model for the broadband Crab nebula spectrum: microscopic interpretation

EPJ Web of Conferences, 2017
We develop a simple two-zone interpretation of the broadband baseline Crab nebula spectrum between 10−5 eV and ~ 100 TeV by using two distinct log-parabola energetic electrons distributions.

Complex molecules in the Orion Kleinmann-Low nebula

BIO Web of Conferences, 2014
In the framework of the delivery to the early Earth of extraterrestrial molecules, we have studied complex molecular species toward the Orion Kleinmann-Low nebula. This nebula is rich in molecules as well as in nascent stars and planetary systems.
