On the APOGEE DR14 sodium spread in the Galactic open cluster NGC188
(American Astronomical Society, 2019-07)
[Na/Fe] is a flagship among chemical abundances as a good indicator of the existence of multiple populations in globular clusters, with spreads of up to 0.6 dex and more; no globular cluster having a null spread (Gratton ...
AzTEC millimetre survey of the COSMOS field – I. Data reduction and source catalogue
(Monthly notices of the royal astronomical society, 2008)
The Automatic Learning for the Rapid Classification of Events (ALeRCE) Alert Broker
(American Astronomical Society (Aas), 2021)
We introduce the Automatic Learning for the Rapid Classification of Events (ALeRCE) broker, an astronomical alert broker designed to provide a rapid and self-consistent classification of large etendue telescope alert ...
Host galaxies of long gamma-ray bursts in the Millennium Simulation
(Wiley Blackwell Publishing, Inc, 2010-10)
In this work, we investigate the nature of the host galaxies of long Gamma-Ray bursts (LGRBs) using a galaxy catalogue constructed from the Millennium Simulation. We developed a LGRB synthetic model based on the hypothesis ...
H2O southern galactic plane survey (HOPS): Paper III – properties of dense molecular gas across the inner milky way
(Oxford University Pres, 2017)
The H2O Southern Galactic Plane Survey (HOPS) has mapped 100 deg(2) of the Galactic plane for water masers and thermal molecular line emission using the 22 m Mopra telescope. We describe the automated spectral-line fitting ...
Artificial Intelligence in astronomy: machine learning and deep learning approaches to DESI data
(Universidad de los AndesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2023-07-11)
Artificial Intelligence (AI) has shown promise in advancing fundamental physics knowledge, from particle physics to cosmology. The significant advancements in AI over the last decade have been increasingly applied to solve ...
Machine learning on difference image analysis: A comparison of methods for transient detection
(Elsevier, 2019-07)
We present a comparison of several Difference Image Analysis (DIA) techniques, in combination with Machine Learning (ML) algorithms, applied to the identification of optical transients associated to gravitational wave ...
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the Extended Baryon Oscillation Spectroscopic Survey and from the Second Phase of the Apache Point Observatory Galactic Evolution Experiment
(2018)
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release ...
Constraints on the Physical Properties of GW190814 through Simulations Based on DECam Follow-up Observations by the Dark Energy Survey
(IOP Publishing Ltd, 2020-09)
On 2019 August 14, the LIGO and Virgo Collaborations detected gravitational waves from a black hole and a 2.6 solar mass compact object, possibly the first neutron star-black hole merger. In search of an optical counterpart, ...
Depthwise convolutional neural network for multiband automatic quasars classification in ATLAS
(2023)
In recent years, the astronomical scientific community has made significant efforts to automate quasars' detection. Automatic classification of these objects is challenging since they are very distant and appear as point ...
