FOUR NEW STELLAR DEBRIS STREAMS IN THE GALACTIC HALO [PDF]

open access: yesThe Astrophysical Journal, 2009
We report on the detection of four new stellar debris streams and a new dwarf galaxy candidate in the Sloan Digital Sky Survey. Three of the streams, ranging between 3 and 15 kpc in distance and spanning between 37 and 84 degrees on the sky, are very narrow and are most probably tidal streams originating in extant or disrupted globular clusters.

Galactic-Seismology Substructures and Streams Hunter with LAMOST and Gaia. I. Methodology and Local Halo Results

open access: yesThe Astrophysical Journal
We present a novel, deep-learning-based method—dubbed Galactic-Seismology Substructures and Streams Hunter, or GS ^3 Hunter for short—to search for substructures and streams in stellar kinematics data.

Stellar streams around the Magellanic Clouds [PDF]

open access: yes, 2016
Using Blue Horizontal Branch stars identified in the Dark Energy Survey Year 1 data, we report the detection of an extended and lumpy stellar debris distribution around the Magellanic Clouds.

Confinement in Metal‐Organic Frameworks as a Route to Harnessing Liquid Barocalorics in the Solid‐State

open access: yesAdvanced Functional Materials, EarlyView.
Encapsulation of solid–liquid barocalorics (BC) within MOFs harnesses their colossal BC performance whilst allowing active control of BC properties through BC‐MOF interactions. ABSTRACT Barocaloric (BC) effects at liquid–vapor transitions in hydrofluorocarbons drive most commercial technologies used for heating and cooling in the heating, ventilation ...

Swarming in stellar streams: Unveiling the structure of the Jhelum stream with ant colony-inspired computation

open access: yesAstronomy & Astrophysics
The halo of the Milky Way galaxy hosts multiple dynamically coherent substructures known as stellar streams that are remnants of tidally disrupted orbiting systems such as globular clusters (GCs) and dwarf galaxies (DGs). A particular case is that of the Jhelum stream, which is known for its unusual and complex morphology. Using the available data from

Detecting the Disruption of Dark-Matter Halos with Stellar Streams [PDF]

open access: yesPhysical Review Letters, 2016
Narrow stellar streams in the Milky Way halo are uniquely sensitive to dark-matter subhalos, but many of these subhalos may be tidally disrupted. I calculate the interaction between stellar and dark-matter streams using analytical and $N$-body calculations, showing that disrupting objects can be detected as low-concentration subhalos.

M-dwarf stellar winds : the effects of realistic magnetic geometry on rotational evolution and planets [PDF]

open access: yes, 2014
AAV acknowledges support from a Royal Astronomical Society Fellowship. JM acknowledges support from a fellowship of the Alexander von Humboldt foundation.We perform three-dimensional numerical simulations of stellar winds of early-M-dwarf stars.

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

StarStream: Automatic Detection Algorithm for Stellar Streams

open access: yesThe Astrophysical Journal
The Gaia mission has led to the discovery of over 100 stellar streams in the Milky Way, most of which likely originated from globular clusters (GCs).
