Lyman Alpha Emitting Galaxies in the Nearby Universe [PDF]

Publications of the Astronomical Society of Australia, 2015
AbstractThe Lyman alpha emission line (Lyα) of neutral hydrogen (Hi) is intrinsically the brightest emission feature in the spectrum of astrophysical nebulae, making it a very attractive observational feature with which to survey galaxies. Moreover as an ultraviolet resonance line, Lyα possesses several unique characteristics that make it useful to ...

Chemodynamics of Lyman alpha emitters, Lyman break galaxies and elliptical galaxies [PDF]

EAS Publications Series, 2007
We report an ultra-high-resolution simulation that follows evolution from the earliest stages of galaxy formation through the period of dynamical relaxation. The bubble structures of gas revealed in our simulation ($< 3\times 10^8$ years) resemble closely the high-redshift Lyman $α$ emitters (LAEs).

Observing Lyman alpha emitters - How does Lyman alpha escape from galaxies?

, 2016
The Lyman alpha (Lyα) emission line has grown to become one of the most successful tools for finding galaxies at high redshift. At redshifts corresponding to the early cosmic times of reionization and primeval galaxy formation, the wavelength of Lyα is still accessible with ground-based facilities.

Cystic fibrosis year in review 2022

Pediatric Pulmonology, Volume 58, Issue 11, Page 3013-3022, November 2023., 2023
Abstract Remarkable medical advancements have been made for people with cystic fibrosis (CF) in recent years, with an abundance of research continuing to be conducted worldwide. With concern for limitations in access to highly effective CFTR modulators, as well as the recent Coronavirus Disease‐19 pandemic, there has been a consistent effort to ...

PAWS and POCO: NIR Astrophotonic Instruments for Astronomy

Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023
Abstract For near‐infrared ground and space‐based astronomy, compact photonic devices can replace the large bulk optical components in spectrographs, frequency combs, beam combiners, and sky subtraction filters, thus saving cost, reducing volume, weight, and power requirements.

Characterizing Strongly-Lensed Lyman-Alpha Galaxies at z > 4

, 2023
Lyman-alpha is one of the most important tools for studying star-forming regions in young galaxies. As Hydrogen's brightest recombination line, it is an excellent tracer for star formation during the Epoch of Reionization.

Future Climate Under CMIP6 Solar Activity Scenarios

Earth and Space Science, Volume 10, Issue 7, July 2023., 2023
Abstract Predictions of solar activity in the future are difficult to make due to the chaotic state of solar dynamo and the high nonlinearity of physical processes on the Sun. Therefore, the Climate Intercomparison Project Phase 6 (CMIP6) used a statistical approach and recommended two different solar forcing scenarios for the simulations.

Lyman break galaxies and the star formation rate of the Universe at z ~ 6 [PDF]

, 2003
We determine the space density of UV-luminous starburst galaxies at z≈ 6 using deep HST ACS SDSS-i′ (F775W) and SDSS-z′ (F850LP) and VLT ISAAC J and Ks band imaging of the Chandra Deep Field South.

Revisiting the emission line source detection problem in integral field spectroscopic data

Astronomische Nachrichten, Volume 344, Issue 5, June 2023., 2023
Abstract We present a 3‐dimensional matched filtering approach for the blind search of faint emission‐line sources in integral‐field spectroscopic datasets. The filter is designed to account for the spectrally rapidly varying background noise due to the telluric air glow spectrum.
