A ~6 Mpc overdensity atz≃ 2.7 detected along a pair of quasar sight lines: filament or protocluster? [PDF]
Astronomy & Astrophysics, 2014 Simulations predict that gas in the intergalactic medium (IGM) is distributed in filamentary structures that connect dense galaxy clusters and form the cosmic web. These structures of predominantly ionized hydrogen are difficult to observe directly due to their lack of emitting regions.

THE END OF HELIUM REIONIZATION AT z ≃ 2.7 INFERRED FROM COSMIC VARIANCE IN HST /COS He II Lyα ABSORPTION SPECTRA [PDF]
The Astrophysical Journal, 2011 We report on the detection of strongly varying intergalactic HeII absorption in HST/COS spectra of two z~3 quasars. From our homogeneous analysis of the HeII absorption in these and three archival sightlines, we find a marked increase in the mean HeII effective optical depth from tau~1 at z~2.3 to tau>5 at z~3.2, but with a large scatter of 2< ...

Rerunning OCR: A Machine Learning Approach to Quality Assessment and Enhancement Prediction [PDF]
Journal of Data Mining and Digital Humanities, 2022 Iterating with new and improved OCR solutions enforces decision making when it comes to targeting the right candidates for reprocessing. This especially applies when the underlying data collection is of considerable size and rather diverse in terms of ...

OGLE-2018-BLG-0799Lb: a q ∼ 2.7 × 10−3 planet with Spitzer parallax [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We report the discovery and analysis of a planet in the microlensing event OGLE-2018-BLG-0799. The planetary signal was observed by several ground-based telescopes, and the planet-host mass ratio is q = (2.65 ± 0.16) × 10−3. The ground-based observations yield a constraint on the angular Einstein radius θE, and the microlensing ...

Romanian Question Answering Using Transformer Based Neural Networks
Studia Universitatis Babes-Bolyai: Series Informatica, 2022 Question answering is the task of predicting answers for questions based on a context paragraph. It has become especially important, as the large amounts of textual data available online requires not only gathering information but also the task of ...
