Strong [O iii] λ5007 Compact Galaxies Identified from SDSS DR16 and Their Scaling Relations

The Astronomical Journal, 2023
Green-pea galaxies are a special class of star-forming compact galaxies with strong [O iii ] λ 5007 and considered as analogs of high-redshift Ly α -emitting galaxies and potential sources for cosmic reionization.

On the formation of lines in quantum phase space

Journal of Physics A: Mathematical and Theoretical, 2023
Abstract We theoretically study the formation of lines in phase space using Wigner’s distribution W . In trapped quantum systems such lines form generically, crisscrossing phase space

Central line-associated bloodstream infections: Effect of patient and pathogen factors on outcome

Journal of Global Infectious Diseases, 2023
Introduction: Patients on central lines are often having multiple morbidities, and invasive devices provide a niche for biofilm formation, which makes central line-associated bloodstream infections (CLABSIs), a serious concern in health-care settings ...

THE FORMATION OF THE Hα LINE IN THE SOLAR CHROMOSPHERE [PDF]

The Astrophysical Journal, 2012
We use state-of-the-art radiation-MHD simulations and 3D non-LTE radiative transfer computations to investigate \Halpha\ line formation in the solar chromosphere and apply the results of this investigation to develop the potential of \Halpha\ as diagnostic of the chromosphere.

Line formation in the wind of Alpha Cygni [PDF]

International Astronomical Union Colloquium, 1981
AbstractWe summarize the results of recent IUE observations of the spectra of α Cygni and discuss possible explanations for the Doppler-shifted pure absorption profiles in the resonance lines of the singly ionized metals. The results of detailed modeling for MgII λ 2795, 2802 are presented, and discussed in the context of observations of α Cyg in the ...

Cell division promotes efficient retrotransposition in a stable L1 reporter cell line [PDF]

, 2013
Background: Long interspersed element type one (L1) actively modifies the human genome by inserting new copies of itself. This process, termed retrotransposition, requires the formation of an L1 ribonucleoprotein (RNP) complex, which must enter the ...

Biological clocks and incremental growth line formation in dentine

, 2020
Dentine‐ and enamel‐forming cells secrete matrix in consistent rhythmic phases, resulting in the formation of successive microscopic growth lines inside tooth crowns and roots. Experimental studies of various mammals have proven that these lines are laid

Cyclotron line formation in a relativistic outflow [PDF]

AIP Conference Proceedings, 1996
There is mounting evidence that, if gamma-ray bursters are Galactic in origin, they are located in a Galactic corona at distances greater than 100 kpc. This has created a need to explore new models of cyclotron line formation. In most previous calculations the line-forming region was modeled as a static slab of plasma, optically thin to continuum ...

Optimizing End-to-End System Performance for Millimeter and Submillimeter Spectroscopy of Protostars: Wideband Heterodyne Receivers and Sideband-Deconvolution Techniques for Rapid Molecular-Line Surveys [PDF]

, 2011
This thesis describes the construction, integration, and use of a new 230-GHz ultra-wideband heterodyne receiver, as well as the development and testing of a new sideband-deconvolution algorithm, both designed to enable rapid, sensitive molecular-line ...

Non-LTE LINE FORMATION FOR S I

Odessa Astronomical Publications, 2008
A comprehensive model atom for non-LTE line formation calculations for neutral sulfur in the spectra of F-K stars is presented. All the calculations were made using the 65-level atomic model of S I and Kurucz's atmosphere models with Teff = 5000 ÷ 6500 K,
