Characteristics of the flankmagnetopause: Cluster observations

open access: yes, 2016
The magnetopause is a current sheet forming the boundary between the geomagnetic field on one side and the shocked solar wind on the other side. This paper discusses properties of the low-latitude dawn and dusk flanks of the magnetopause.

On the dusty proximate damped Lyman-α system toward Q 2310−3358 at z = 2.40

open access: yesAstronomy & Astrophysics
Quasar absorption systems not only affect the way quasars are selected, but also serve as key probes of galaxies, providing insight into their chemical evolution and interstellar medium (ISM). Recently, a method based on Gaia astrometric measurements has

An Atlas of Color-selected Quiescent Galaxies at z > 3 in Public JWST Fields

open access: yesThe Astrophysical Journal, 2023
We present the results of a systematic search for candidate quiescent galaxies in the distant universe in 11 JWST fields with publicly available observations collected during the first 3 months of operations and covering an effective sky area of ∼145 ...

Double trouble: Two spectroscopically confirmed low-mass quiescent galaxies at z > 5 in overdensities

open access: yesAstronomy & Astrophysics
We present the discovery of two low-mass, high-redshift quiescent galaxies, GS-z5-Q1 and COS-z5-Q1, using JWST NIRSpec spectroscopy alongside NIRCam and MIRI photometry.

The Dawn of Galaxies

open access: yes, 2003
The development of primordial inhomogeneities into the non-linear regime and the formation of the first astrophysical objects within dark matter halos mark the transition from a simple, neutral, cooling universe -- described by just a few parameters ...

On the Blackbody Spectrum of Kilonovae

open access: yesThe Astrophysical Journal, 2023
The early spectra of the kilonova AT2017gfo have a remarkably smooth blackbody continuum, which reveals information on the thermal properties and radioactive heating within the ejecta.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Spatially Resolved Properties of Galaxies at 5 < z < 9 in the SMACS 0723 JWST ERO Field

open access: yesThe Astrophysical Journal, 2023
We present the first spatially resolved measurements of galaxy properties in the JWST ERO SMACS 0723 field. We perform a comprehensive analysis of five 5 < z < 9 galaxies with spectroscopic redshifts from NIRSpec observations.
