Weak In‐Plane Ferromagnetism and Electronic Nematicity in the Distorted Triple‐Q Magnetic Phase of Co1/3TaS2

Advanced Materials, EarlyView.
Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

A Map of the Outer Gas Disk of the Galaxy with Direct Distances from Young Stars

The Astrophysical Journal
For more than 50 yr, astronomers have mapped the neutral hydrogen gas in the Galaxy assuming kinematically derived distances. We employ the distances of nearby young stars, which trace the gas from which they formed, in longitude–latitude–velocity space ...

FERMI GBM CAPABILITIES FOR MULTI-MESSENGER TIME-DOMAIN ASTRONOMY [PDF]

EAS Publications Series, 2013
Owing to its wide sky coverage and broad energy range, the Fermi Gamma-ray Burst Monitor (GBM) is an excellent observer of the transient hard X-ray sky. GBM detects about 240 triggered Gamma-Ray Bursts (GRBs) per year, including over 30 which also trigger the Swift Burst Alert Telescope (BAT).

Exploring Time Domain Multi-Messenger Astronomy through the Virtual Observatory

, 2019
International audienceWhat do Cepheid stars, Binary Neutron stars, Supernovae explosions and Active Galactic Nuclei have in common? They are all variable objects, although the physical processes and the associated time-scales that govern their ...

Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

Advanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Time domain astronomy from Dome C: results from ASTEP [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractASTEP (Antarctic Search for Transiting Exo Planets) is a research program funded mainly by French ANR grants and by the French Polar Institute (IPEV), dedicated to the photometric study of exoplanetary transits from Antarctica.The preliminary “pathfinder” instrument ASTEP–South is described in another communication (Crouzet et al., these ...

Poly(Alkoxythiophene) Rod‐Coil Block Copolymers for Organic Electrochemical Transistors

Advanced Materials, EarlyView.
We present the first synthesis of poly(3‐alkoxythiophene) rod‐coil block copolymers as a new architecture for OMIECs. Incorporating PEG and PLLA coils can enhance device performance beyond the homopolymer. The figure‐of‐merit depends uniquely on coil length.

Time-domain Astronomy with the GMRT: uGMRT to eGMRT [PDF]

Proceedings of the International Astronomical Union, 2017
AbstractThe upgraded GMRT (uGMRT) with its unprecedented sensitivity and high figure of merit, is expected to result in the discovery of a large population of pulsars including pulsars of previously unknown type. In the phase-2 of the GMRT High Resolution Southern Sky (GHRSS) survey with the uGMRT we will reach 1/4th of sensitivity of the SKA Phase-1 ...

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

Advanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Nineteenth century astronomy at the US Naval Academy [PDF]

, 2002
During the 1850s the newly-formed U.S. Naval Academy in Annapolis, Maryland, acquired a small observatory featuring a 19.7-cm (7.75-in.) Clark refractor, transit telescopes, and an astronomical clock.
