New 20-cm radio-continuum study of the small Magellanic cloud - part III: Compact Hii regions [PDF]

open access: yesSerbian Astronomical Journal, 2012
We present and discuss a new catalogue of 48 compact Hii regions in the Small Magellanic Cloud (SMC) and a newly created deep 1420 MHz (λ=20 cm) radio-continuum image of the N19 region located in the southwestern part of the SMC.

Adding gravitational memory to waveform catalogs using BMS balance laws [PDF]

open access: yesPhysical Review D, 2020
Accurate models of gravitational waves from merging binary black holes are crucial for detectors to measure events and extract new science. One important feature that is currently missing from the Simulating eXtreme Spacetimes (SXS) Collaboration's ...

A critical assessment of gene catalogs for metagenomic analysis

open access: yesBioinform., 2021
Motivation Microbial gene catalogs are data structures that organize genes found in microbial communities, providing a reference for standardized analysis of the microbes across samples and studies. Although gene catalogs are commonly used, they have not
