A Measurement of Small Scale Structure in the 2.2 < z < 4.2 Lyman-alpha Forest (2009)
Lidz, Adam, Dall'Aglio, Aldo, McQuinn, Matthew, Fechner, Cora, Zaldarriaga, Matias, ...
The amplitude of fluctuations in the Ly-a forest on small spatial scales is sensitive to the temperature of the IGM and its spatial fluctuations. The temperature of the IGM and its spatial variations...
Dall'Aglio, Aldo, Wisotzki, Lutz, Worseck, Gabor
(Abridged) We present the results from the largest investigation to date of the proximity effect in the HI Lyalpha forest, using the fifth SDSS data release. The sample consists of 1733 QSOs at...
Analysis of methods for detecting the proximity effect in quasar spectra (2009)
Dall'Aglio, Aldo, Gnedin, Nickolay Y.
Using numerical simulations of structure formation, we investigate multiple methods of determining the strength of the proximity effect in the HI Lyalpha forest. We analyze three high resolution...
Dall'Aglio, Aldo, Wisotzki, Lutz, Worseck, Gabor
We used 40 high resolution, high S/N QSO spectra at 2.1
The line-of-sight proximity effect in individual quasar spectra (2008)
Dall'Aglio, Aldo, Wisotzki, Lutz, Worseck, Gabor
We exploit a set of high signal-to-noise (~70), low-resolution (R~800) quasar spectra to search for the signature of the so-called proximity effect in the HI Ly alpha forest. Our sample consists of...
