EBHIS Local Volume Galaxy Hi Survey (LVGHIS)

Astronomische Nachrichten, EarlyView.
ABSTRACT Here, we present the “Local Volume Galaxy Hi Survey” (LVGHIS). It is based on the first data release of the Milky Way portion of the Effelsberg Bonn Hi‐Survey (EBHIS). We homogeneously measured the mass and dynamics of the local volume galaxies within the radial velocity limit of |vLSR|≤600kms−1$$ \mid {v}_{\mathrm{LSR}}\mid \le 600\kern0.6em \

Implementation of a spherical double-plasma-mirror telescope for a multi-petawatt laser

High Power Laser Science and Engineering
High-power laser beamlines typically operate with fixed focusing conditions, limiting the focal spot size and peak intensity. To mitigate these restrictions, prior studies used curved plasma mirrors to adjust the F-number to a specific value.

Case Study of a Fly's Eye Homogenizer for the Calibration Illumination of Integral Field Units

Astronomische Nachrichten, EarlyView.
ABSTRACT Integral‐field unit spectrographs require a homogeneous calibration illumination of the field of view for proper flat and wavelength calibration (e.g., BlueMUSE which is currently under development for the VLT). This article presents the adaptation of a fly's eye homogenizer, frequently used in laser applications, to this task in astronomical ...

Statistics of the Optical Turbulence from the Micrometeorological Measurements at the Baykal Astrophysical Observatory Site

Atmosphere, 2019
The paper focuses on the investigations of the optical turbulence structure. The distributions of the repeatability of the structure characteristic of the air refractive index are obtained. A scenario of decreasing the intensity of the optical turbulence

Listening to Hong Kong children's perspectives through pretend play

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

The absence of women's scientific contributions in core UK pre‐university science qualifications

British Educational Research Journal, EarlyView.
Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...
