The Massive Legal Embedding Benchmark (MLEB)
Umar Butler, Abdur-Rahman Butler, Adrian Lucas Malec
We present the Massive Legal Embedding Benchmark (MLEB), the largest, most diverse, and most comprehensive open-source benchmark for legal information retrieval to date. MLEB consi…
Precise limits on cosmological variability of the fine-structure constant with zinc and chromium quasar absorption lines
Michael T. Murphy, Adrian L. Malec, J. Xavier Prochaska
The strongest transitions of Zn and CrII are the most sensitive to relative variations in the fine-structure constant () among the transitions commonly observed in quasar abs…
Three-dimensional shapelets and an automated classification scheme for dark matter haloes
C. J. Fluke, A. L. Malec, P. D. Lasky +1
We extend the two-dimensional Cartesian shapelet formalism to d-dimensions. Concentrating on the three-dimensional case, we derive shapelet-based equations for the mass, centroid,…
First constraint on cosmological variation of the proton-to-electron mass ratio from two independent telescopes
Freek van Weerdenburg, Michael T. Murphy, Adrian L. Malec +2
A high signal-to-noise spectrum covering the largest number of hydrogen lines (90 H2 lines and 6 HD lines) in a high redshift object was analyzed from an observation along the sigh…
A High-Velocity Narrow Absorption Line Outflow in the Quasar J212329.46-005052.9
F. Hamann, N. Kanekar, J. X. Prochaska +5
We report on a variable high-velocity narrow absorption line outflow in the redshift 2.3 quasar J2123-0050. Five distinct outflow systems are detected with velocity shifts from -97…
Cosmological concordance or chemical coincidence? Deuterated molecular hydrogen abundances at high redshift
J. Tumlinson, A. L. Malec, R. F. Carswell +8
We report two detections of deuterated molecular hydrogen (HD) in QSO absorption-line systems at . Toward J2123-0500, we find (HD) for a sub-DLA with me…
