Measuring the Quantum State of Dark Matter

Annalen der Physik, Volume 536, Issue 1, January 2024.
It is demonstrated how the time series obtained from searches for ultralight bosonic dark matter, such as the axion, can be used to determine whether it is in a coherent or incoherent quantum state. Abstract It is shown how the time series obtained from searches for ultralight bosonic dark matter (DM), such as the axion, can be used to determine ...

Strong Lyman continuum emitting galaxies show intense C 

, 2022
Using the Space Telescope Imaging Spectrograph, we have obtained ultraviolet spectra from ∼1200 to 2000 Å of known Lyman continuum (LyC) emitting galaxies at low redshift (z ∼ 0.3 − 0.4) with varying absolute LyC escape fractions (fesc ∼ 0.01 − 0.72 ...

The Size Evolution and the Size–Mass Relation of Lyα Emitters across 3 ≲ z< 7 as Observed by JWST

The Astrophysical Journal
Understanding the morphological structures of Ly α emitters (LAEs) is crucial for unveiling their formation pathways and the physical origins of Ly α emission. However, the evolution of their sizes and structural scaling relations remains debated.

THE LYMAN ALPHA MORPHOLOGY OF LOCAL STARBURST GALAXIES: RELEASE OF CALIBRATED IMAGES [PDF]

The Astronomical Journal, 2009
We present reduced and calibrated high resolution Lyman-alpha (Lya) images for a sample of 6 local star forming galaxies. Targets were selected to represent a range in luminosity and metallicity and to include both known Lya emitters and non-emitters.

ALMA observations of Lyman Alpha Blobs

, 2019
We will introduce our dust and CO observations of high-z extended Lyman Alpha nebulae (Lyman Alpha Blobs or LABs). LABs are the best targets to study the relation between galaxy formation and the circum galactic medium.

The cosmic web in Lyman-alpha emission

, 2022
We develop a comprehensive theoretical model for Lyman-alpha emission, from the scale of individual Lyman-alpha emitters (LAEs) to Lyman-alpha halos (LAHs), Lyman-alpha blobs (LABs), and Lyman-alpha filaments (LAFs) of the diffuse cosmic web itself.

A Spectral Atlas of Lyα Emitters at z = 5.7 and z = 6.6

The Astrophysical Journal
We present two uniformly observed spectroscopic samples of Ly α emitters (LAEs; 127 at z = 5.7 and 82 at z = 6.6), which we use to investigate the evolution of the LAE population at these redshifts.

Spatially resolved spectroscopy of faint star-forming galaxies & their environments in the high redshift universe [PDF]

, 2011
This thesis is concerned with the spectroscopic observations of distant galaxies, 1 < z < 5. The galaxies presented here are intrinsically faint such that their ux is dominated by ordinary star formation rather than galaxy-galaxy merging and/or ...

The Web Epoch of Reionization Lyα Survey (WERLS). I. MOSFIRE Spectroscopy of z ∼ 7–8 Lyα Emitters

The Astrophysical Journal
We present the first results from the Web Epoch of Reionization Ly α Survey (WERLS), a spectroscopic survey of Ly α emission using Keck I/MOSFIRE and LRIS.
