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 ...

The 100 strongest radio point sources in the field of the Large Magellanic Cloud at 1.4 GHz [PDF]

open access: yesSerbian Astronomical Journal, 2009
We present the 100 strongest 1.4 GHz point sources from a new mosaic image in the direction of the Large Magellanic Cloud (LMC). The observations making up the mosaic were made using Australia Telescope Compact Array (ATCA) over a ten year period and ...

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

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.

Large Synoptic Survey Telescope: From science drivers to reference design [PDF]

open access: yesSerbian Astronomical Journal, 2008
In the history of astronomy, major advances in our understanding of the Universe have come from dramatic improvements in our ability to accurately measure astronomical quantities. Aided by rapid progress in information technology, current sky surveys are

Independent analysis of μδ data of ILS and INDLS catalogs to obtain the spin of the bright Gaia DR2 reference frame [PDF]

open access: yesSerbian Astronomical Journal, 2021
The Gaia DR2 reference frame should be without relative rotation to the quasars (QSOs) and consistent with the International Celestial Reference System (ICRS).

Measuring chandler wobble amplitude variations using IERS EOP C04 data [PDF]

open access: yesSerbian Astronomical Journal, 2023
We analyzed the Earth's long-term polar motion using the time series IERS EOP C04 (International Earth Rotation and Reference Systems Service - IERS; Earth Orientation Parameters - EOP; Combination of four (04) techniques - C04), from 1984 to ...

Solar flare catalog based on SDO/AIA EUV images: Composition and correlation with GOES/XRS X-ray flare magnitudes

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Supervised Machine Learning (ML) models for solar flare prediction rely on accurate labels for a given input data set, commonly obtained from the GOES/XRS X-ray flare catalog. With increasing interest in utilizing ultraviolet (UV) and extreme ultraviolet

Cross-correlating galaxy catalogs and gravitational waves: A tomographic approach [PDF]

open access: yes, 2020
Unveiling the origin of the coalescing binaries detected via gravitational waves (GW) is challenging, notably if no multi-wavelength counterpart is detected.
