COMET-LF: a compartmental model of dynamics of infection, disease, and elimination strategies for lymphatic filariasis [PDF]

open access: yesBMC Infectious Diseases
Background Lymphatic filariasis (LF) is a mosquito-borne disease caused by filarial worms. The WHO has targeted LF elimination by 2030. Mathematical models can help evaluate and guide elimination strategies. Methods We developed a new compartmental model—

Dynamical Simulation of the Interstellar Comet 3I/ATLAS

open access: yesThe Astrophysical Journal Letters
Comet 3I/ATLAS, also known as C/2025 N1, was discovered on 2025 July 1 UT by NASA Asteroid Terrestrial-impact Last Alert System (ATLAS), with a v _∞ ∼ 58 km s ^−1 . This is the fastest among the three interstellar objects discovered so far. In this work,

Status of the COMET experiment [PDF]

open access: yesEPJ Web of Conferences, 2023
The COMET (COherent Muon to Electron Transition) experiment, currently being built in Tokai, Japan, will search for the coherent neutrinoless transition of muons to electrons in the coulomb field of atomic nuclei.

Recurring Activity Discovered on Quasi-Hilda 2009 DQ118

open access: yesThe Astrophysical Journal Letters, 2023
We have discovered two epochs of activity on quasi-Hilda 2009 DQ _118 . Small bodies that display comet-like activity, such as active asteroids and active quasi-Hildas, are important for understanding the distribution of water and other volatiles ...

Dynamics of Comets [PDF]

open access: yesSymposium - International Astronomical Union, 1992
The gravitational processes affecting the dynamics of comets are reviewed. At great distances from the Sun the motion of comets is primarily affected by the vertical component of the galactic field, as well as by encounters with stars and giant molecular clouds.

The Gateway from Centaurs to Jupiter-family Comets: Thermal and Dynamical Evolution

open access: yesThe Astrophysical Journal, 2023
It was recently proposed that there exists a “gateway” in the orbital parameter space through which Centaurs transition to Jupiter-family comets (JFCs).

(523599) 2003 RM: The Asteroid that Wanted to be a Comet

open access: yesThe Planetary Science Journal, 2023
We report a statistically significant detection of nongravitational acceleration on the subkilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences favorable observing apparitions every 5 yr.

X-Ray Emission Spectroscopy Analysis for Near-Asteroid Belt of Atmospheric of the Comets

open access: yesIraqi Journal of Physics, 2022
         According to Chandra Survey Observatory Near-Asteroid Belt Comets, the solar wind's contact with the comet produces a variety of spectral characteristics. The study of X-ray spectra produced by charge exchange is presented here. The spectrum of
