Blind QSO reconstruction challenge: Exploring methods to reconstruct the Ly emission line of QSOs
Bradley Greig, Sarah E. I. Bosman, Frederick B. Davies +9
Reconstructing the intrinsic Ly line flux from high- QSOs can place constraints on the neutral hydrogen content of the intergalactic medium during reionisation. There are now…
A ghostly damped Ly system revealed by metal absorption lines
Hassan Fathivavsari, Patrick Petitjean, Siwei Zou +4
We report the discovery of the first 'ghostly' damped Ly absorption system (DLA), which is identified by the presence of absorption from strong low-ion species at $z_{\rm abs}=1…
Spectral atlases of the Sun from 3980 to 7100 Å at the center and at the limb
Hassan Fathivavsari, Ali Ajabshirizadeh, Serge Koutchmy
In this work, we present digital and graphical atlases of spectra of both the solar disk-center and of the limb near the Solar poles using data taken at the UTS-IAP & RIAAM (the Un…
