Time-integrated Southern-sky Neutrino Source Searches with 10 yr of IceCube Starting-track Events at Energies Down to 1 TeV

open access: yesThe Astrophysical Journal
In the IceCube Neutrino Observatory, a signal of astrophysical neutrinos is obscured by backgrounds from atmospheric neutrinos and muons produced in cosmic-ray interactions. IceCube event selections used to isolate the astrophysical neutrino signal often

Exploring the interstellar medium of NGC 891 at millimeter wavelengths using the NIKA2 camera [PDF]

open access: yesEPJ Web of Conferences
In the framework of the IMEGIN Large Program, we used the NIKA2 camera on the IRAM 30-m telescope to observe the edge-on galaxy NGC 891 at 1.15 mm and 2 mm and at a FWHM of 11.1” and 17.6”, respectively.

Re-identification of G35.6-0.4 as a supernova remnant

open access: yes, 2009
G35.6-0.4 is an extended radio source in the Galactic plane which has previously been identified as either a supernova remnant or an HII region. Observations from the VLA Galactic Plane Survey at 1.4 GHz with a resolution of 1 arcmin allow the extent of ...

Thickness‐Dependent Skyrmion Evolution in Fe3GeTe2 During Magnetization Reversal

open access: yesAdvanced Functional Materials, EarlyView.
Thickness‐ and field‐dependent magnetic domain behavior in 2D van der Waals Fe3GeTe2 is studied using Lorentz TEM and micromagnetic simulations. A patch‐like domain phase evolves from skyrmions during magnetization reversal, and step edges between thickness regions act as pinning sites.

Z-Distribution and Period Gradient of Classical Cepheids in the Galactic Plane [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1986
The z-coordinate distribution of cepheids was studied and the finding of Fernie(1968) that the Cepheid layer is inclined toward a formal Galactic plane and the Sun is located above the cepheid plane was confirmed.

The AMANOGAWA-2SB Galactic Plane Survey I. Data on the Galactic Equator [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2010
Abstract Using a waveguide-type sideband-separating receiver (2SB receiver) on the Tokyo-NRO 60-cm telescope (renamed the AMANOGAWA telescope), we carried out simultaneous observations in the $^{12}$CO ($J =$ 2–1) and $^{13}$CO ($J =$ 2–1) lines over the galactic plane $l =$ 10$^\circ$–245$^\circ$ along $b =$ 0$^\circ$ with a 3$'\!\!.$75

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Impact of Lattice Heterogeneity on Broadband Optical Retardation in Stacked 2D Perovskite Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
It is shown that interfaces between organic and inorganic layers govern long‐range stacking disorder and in‐plane anisotropy in 2D metal‐halide perovskites. By comparing single‐cation AB‐AB and ordered mixed‐cation ABCD‐ABCD stackings, SCXRD reveals enhanced mosaicity, while optics confirm high birefringence.

Stäackel-type Dynamic Model of the Galaxy Based on Maser Kinematic Data

open access: yesOpen Astronomy, 2016
A dynamic model of the Galaxy is constructed based on kinematic data for masers with trigonometric parallaxes. Maser data is used to compute the model potential in the Galactic plane.
