Bits Missing: Finding Exotic Pulsars Using bfloat16 on NVIDIA GPUs

open access: yesThe Astrophysical Journal Supplement Series, 2023
The Fourier domain acceleration search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy data sets. This paper quantifies the sensitivity impact of reducing numerical precision in the graphics processing unit ...

Computational Infrared Spectroscopy of 958 Phosphorus-Bearing Molecules [PDF]

open access: yes, 2021
Phosphine is now well-established as a biosignature, which has risen to prominence with its recent tentative detection on Venus. To follow up this discovery and related future exoplanet biosignature detections, it is important to spectroscopically detect

Contact residue contributions to interaction energies between SARS-CoV-1 spike proteins and human ACE2 receptors

open access: yesScientific Reports, 2021
Several viruses of the corona family interact, via their spike (S) proteins, with human cellular receptors. Spike proteins of SARS-CoV-1 and SARS-CoV-2 virions, being structurally related but not identical, mediate attachment to the human angiotensin ...

Computer as a Tool in Astronomy Teaching [PDF]

open access: yesInternational Astronomical Union Colloquium, 1998
As yet, astronomy, the most ancient of all sciences, surprisingly is not included in French secondary science classes. Recent trends in favour of a more attractive and motivating scientific education have taken it up.Astronomy has, at all times, been arising curiosity, and now provides a privileged field to scientific approach :•Observation of the ...

Efficient galaxy classification through pretraining

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Deep learning has increasingly been applied to supervised learning tasks in astronomy, such as classifying images of galaxies based on their apparent shape (i.e., galaxy morphology classification) to gain insight regarding the evolution of galaxies.

SAX and Random Projection Algorithms for the Motif Discovery of Orbital Asteroid Resonance Using Big Data Platforms

open access: yesSensors, 2022
The phenomenon of big data has occurred in many fields of knowledge, one of which is astronomy. One example of a large dataset in astronomy is that of numerically integrated time series asteroid orbital elements from a time span of millions to billions ...

Accelerating Dedispersion Using Many-core Architectures

open access: yesThe Astrophysical Journal Supplement Series, 2023
Astrophysical radio signals are excellent probes of extreme physical processes that emit them. However, to reach Earth, electromagnetic radiation passes through the ionized interstellar medium, introducing a frequency-dependent time delay (dispersion) to
