The Second Case of a Major Merger Triggering a Starburst in a Green Pea Galaxy

The Astrophysical Journal
We have used the Karl G. Jansky Very Large Array (VLA) to map H i 21 cm emission from the Green Pea galaxy GP J1148+2546 at z ≈ 0.0451, only the second measurement of the H i spatial distribution of a Green Pea.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Spatially Resolved Modeling of Galactic Hα Emission for Galaxy Clustering

The Astrophysical Journal
Near-infrared spectroscopic surveys target high-redshift emission-line galaxies (ELGs) to probe cosmological scenarios. Understanding the clustering properties of ELGs is essential to derive optimal constraints.

Spectroscopic Studies of Emission Line Galaxies [PDF]

Symposium - International Astronomical Union, 1994
Spectroscopic Observations were made to study 42 emission line objects. The analysis of these long slit spectra shows that 15 out of 42 galaxies are blue compact galaxies (BCGs). 21 of them are starforming or HII galaxies and 3 were found to be normal galaxies.

Progress of metabolomics‐centric multi‐omics research in medicine

iMetaOmics, EarlyView.
The graphical abstract illustrates a holistic roadmap for metabolomics‐centric multi‐omics integration in medical research. The upper panel depicts the technological transition from traditional bulk analysis to high‐resolution single‐cell and spatial methodologies, specifically addressing inherent challenges such as molecular complexity and dynamic ...

Stellar velocity dispersions and emission line properties of SDSS-III/BOSS galaxies [PDF]

, 2012
International audienceWe perform a spectroscopic analysis of 492 450 galaxy spectra from the first two years of observations of the Sloan Digital Sky Survey (SDSS) III/Baryonic Oscillation Spectroscopic Survey (BOSS) collaboration. This data set has been

Discovering galaxies in the early universe

, 2022
Star forming galaxies (SFGs) are expected to be the sources responsible for reionising the Universe, but detailed study of these within the Epoch of Reionisation (EoR, z>6), will only become possible with the long-wavelength coverage and sensitivity of ...

Emission Lines in Star Forming Galaxies [PDF]

Symposium - International Astronomical Union, 1995
Magris et al. (1993, Proceedings of the ESO/OHP Workshop on Dwarf Galaxies, ed. G. Meylan) have combined the spectral evolution population synthesis code of Bruzual & Charlot (1993, ApJ 405, 538) with the multipurpose photoionization-shock code MAPPINGS (Binette et al.

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...
