A Spectroscopic Survey of Lyα Emitters and Lyα Luminosity Function at Redshifts 3.7 and 4.8

open access: yesThe Astrophysical Journal, 2023
We present a spectroscopic survey of Ly α emitters (LAEs) at z ∼ 3.7 and z ∼ 4.8. The LAEs are selected using the narrowband technique based on the combination of deep narrowband and broadband imaging data in two deep fields, and then spectroscopically ...

Observation of laser-assisted electron scattering in superfluid helium

open access: yesNature Communications, 2021
Laser-assisted electron scattering (LAES) is a commonly observed strong field process in gas phase systems. Here the authors use helium droplets with core atoms and molecules to observe increased electron energy due to multiple LAES events within the ...

Lyman Continuum Emission from Spectroscopically Confirmed Lyα Emitters at z ∼ 3.1

open access: yesThe Astrophysical Journal, 2023
We present a study of Lyman continuum (LyC) emission in a sample of ∼150 Ly α emitters (LAEs) at z ≈ 3.1 in the Subaru-XMM Deep Survey field. These LAEs were previously selected using the narrowband technique and spectroscopically confirmed with Ly α ...

LAE-LAE SEBAGAI DESTINASI WISATA ARKEOLOGI DI MAKASSAR, INDONESIA [PDF]

open access: yesJurnal Pariwisata Pesona, 2019
Lae-Lae Island is a small island to the west of Makassar City which is one of the marine tourism destinations. The findings of archaeological remains on the island indicate that the island of Lae-Lae has a new attraction that is different from what is currently and can be developed towards archaeo-tourism. This article intends to describe the potential
