Illuminating the dark universe in the multi-messenger era
The precision era of multi-messenger astronomy, together with modern astrophysical, cosmological, and gravitational wave observations, increasingly points toward the existence of a ``dark" sector that cannot be explained within the framework of the S...

Are astronomical papers with more authors cited more?
Following my previous study of paper length vs. number of citations in astronomy (Stanek 2008), some colleagues expressed an interest in knowing if any correlation exists between citations and the number of authors on an astronomical paper. At leas...
Who asks questions at astronomy meetings?
Over the last decade, significant attention has been drawn to the gender ratio of speakers at conferences, and many meetings are evolving to better reflect the gender balance of the field as a whole. We find that women are significantly under-represe...

Cats vs Dogs, Photons vs Hadrons
In gamma ray astronomy with Cherenkov telescopes, machine learning models are needed to guess what kind of particles generated the detected light, and their energies and directions. The focus in this work is on the classification task, training a sim...

Astronomical seeing - Wikipedia
In astronomy, seeing is the degradation of the image of an astronomical object due to turbulence in the atmosphere of Earth that may become visible as
The Scientific Impact of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (…
Vera C. Rubin Observatory will be a key facility for small body science in planetary astronomy over the next decade. It will carry out the Legacy Survey of Space and Time (LSST), observing the sky repeatedly in u, g, r, i, z, and y over the course of...
Science Spoofs, Physics Pranks and Astronomical Antics
Some scientists take themselves and their work very seriously. However, there are plenty of cases of humour being combined with science. Here I review some examples from the broad fields of physics and astronomy, particularly focusing on practical jo...
Pierre Simon de Laplace (1749–1827) | High Altitude Observatory
Laplace's achievements in applied mathematics and astronomy are many and far reaching. Starting in 1773, he applied his mathematical skills to problems in celestial mechanics.
Glance: A Comprehensive Framework for Galactic Archaeology
A central topic in extragalactic astronomy is understanding the formation and evolutionary histories of galaxies. These systems often comprise multiple structural components with distinct physical and dynamical properties, making it challenging to di...
Cuando la ortodoxia no es lo más relevante: el paisaje de La Gomera y la orientación de su…
We present a study of the relationship between astronomy and landscape centered on the orientation of Christian churches of the island of La Gomera, located in the Canary Archipelago. The fieldwork consisted of measuring the precise coordinates of 38...
flare - WordReference.com Dictionary of English
Astronomy Also called solar flare. a sudden and brief brightening of the solar atmosphere in the vicinity of a sunspot that results from an explosive release of particles and radiation.
How likely is a cyclic universe
I’ve always had an interest in astronomy and Astro physics and am a firm believer in the big bang theory. But I also believe that as the universe reaches a point where there is no longer enough ener...
Learning from 25 years of the extensible N-Dimensional Data Format
The extensible N-Dimensional Data Format (NDF) was designed and developed in the late 1980s to provide a data model suitable for use in a variety of astronomy data processing applications supported by the UK Starlink Project. Starlink applications we...
A Global Citizen of the Skies
Global citizenship plays an important role in today's schools. Many subjects taught in schools have already incorporated such ideas. Science and physics have also followed suit. However, when dealing with astronomy - a topic so seemingly far removed...
Scientific Computing Meets Big Data Technology: An Astronomy Use Case
Scientific analyses commonly compose multiple single-process programs into a dataflow. An end-to-end dataflow of single-process programs is known as a many-task application. Typically, tools from the HPC software stack are used to parallelize these a...
Astronomy of two Indian tribes: Banjaras and Kolams
We report field studies of the astronomical beliefs of two Indian tribes: the Banjaras and the Kolams. The Banjaras are an ancient tribe connected with the gypsies of Europe while the Kolams have been foragers until recently. They share their landsca...
