Donald Lynden-Bell: A Biographical Memoir
Donald Lynden-Bell's many contributions to astrophysics encompass general relativity, galactic dynamics, telescope design and observational astronomy. In the 1960s, his papers on stellar dynamics led to fundamental insights into the equilibria of ell...
Astrophysics Uniquely Enabled by Observations of High-Energy Cosmic Neutrinos
High-energy cosmic neutrinos carry unique information about the most energetic non-thermal sources in the Universe. This white paper describes the outstanding astrophysics questions that neutrino astronomy can address in the coming decade. A companio...

Mid-Infrared Spectral Diagnostics of Nearby Galaxies
The Spitzer Space Telescope is pushing into new frontiers in high redshift astronomy. Closer to home, Spitzer is making an equally large impact on our understanding of galaxy formation and evolution. In this contribution we present mid-infrared dia...
Scientific collaborations in astronomy between amateurs and professionals
As our successful Mons campaign to observe WR140 has shown, there is a strong interest among both amateur and professional astronomers to collaborate on specific scientific questions. I highlight here some recent examples of successful collaborations...
Amateur - Wikipedia
Astronomy, chemistry, history, linguistics, and the natural sciences are among the fields that have benefited from the activities of amateurs. Gregor Mendel was an amateur scientist who never held a …

The spectrum of N$_2$ from 4,500 to 15,700 cm$^{-1}$ revisited with PGOPHER
Using a reference molecular atlas to ensure self-consistency of wavelength calibration is widespread practice. Boesch \& Reiners (Astronomy \& Astrophysics 582 A43 (2015)) reported a line list from a discharge of molecular nitrogen from 4500 to 11000...
Everything you need to know about the Moon - Astronomy.com
Sep 7, 2023 · How big is the Moon? The Moon is Earth’s only permanent natural satellite, and it’s the fifth-largest satellite in our solar system. The Moon’s diameter is approximately 2,160 miles (3,475...
Astroalign: A Python module for astronomical image registration
We present an algorithm implemented in the astroalign Python module for image registration in astronomy. Our module does not rely on WCS information and instead matches 3-point asterisms (triangles) on the images to find the most accurate linear tran...

## TL;DR: Permabanned from r/astronomy for showing the actual math behind this is impossible. They'd rather immediately ban me than have to engage the facts. NASA’s data shows 3I/ATLAS reached ...
Convolutional Neural Networks for Spectroscopic Redshift Estimation on Euclid Data
In this paper, we address the problem of spectroscopic redshift estimation in Astronomy. Due to the expansion of the Universe, galaxies recede from each other on average. This movement causes the emitted electromagnetic waves to shift from the blue p...
Wide Field Imager in Space for Dark Energy and Planets
A wide-field imager in space could make remarkable progress in two very different frontiers of astronomy: dark energy and extra-solar planets. Embedding such an imager on a much larger and more complicated DE mission would be a poor science-approac...
