Molecular Clouds Resolved at the Onset of Cosmic Noon
Bjorn Emonts, Matthew Lehnert, Mingyu Li +10
We present the discovery of seven molecular clouds in the radio galaxy B2 0902+34 at redshift z=3.4. These clouds are detected as CO(0-1) absorption features against the bright rad…
Linear Relations of Finite Length Modules are Shift Equivalent to Maps
Bartosz Furmanek, Filip Oskar Łanecki, Mateusz Przybylski +1
Linear relations, defined as submodules of the direct sum of two modules, can be viewed as objects that carry dynamical information and reflect the inherent uncertainty of sampled…
Local data of elliptic curves under quadratic twist
Alexander J. Barrios, Manami Roy, Nandita Sahajpal +3
Let be the field of fractions of a complete discrete valuation ring with a perfect residue field. In this article, we investigate how the Tamagawa number of changes under…
A Complete Invariant for Shift Equivalence for Boolean Matrices and Finite Relations
Ethan Akin, Marian Mrozek, Mateusz Przybylski +1
We give a complete invariant for shift equivalence for Boolean matrices (equivalently finite relations), in terms of the period, the induced partial order on recurrent components,…
The physical and chemical structure of Sagittarius B2 -- VI. UCHII regions in Sgr B2
Fanyi Meng, Álvaro Sánchez-Monge, Peter Schilke +8
The giant molecular cloud Sagittarius B2 (hereafter SgrB2) is the most massive region with ongoing high-mass star formation in the Galaxy. Two ultra-compact HII (UCHII) regions wer…
The Szymczak Functor on the Category of Finite Sets and Finite Relations
Mateusz Przybylski, Marian Mrozek, Jim Wiseman
The Szymczak functor is a tool used to construct the Conley index for dynamical systems with discrete time. We present an algorithmizable classification of isomorphism classes in t…
