Progress towards COMET Phase-I [PDF]

, 2015
The COMET experiment is designed to search for flavour violation in the charged lepton sector, via the coherent neutrinoless process +A e+A, which can probe a wide variety of BSM physics. Using the new high-power proton beam at J-PARC, the sensitivity of

Biomonitoring of the genotoxic potential of aqueous extracts of soils and bottom ash resulting from municipal solid waste incineration, using the comet and micronucleus tests on amphibian (Xenopus laevis) larvae and bacterial assays (MutatoxR and Ames tests) [PDF]

, 2006
The management of contaminated soils and wastes is a matter of considerable human concern. The present study evaluates the genotoxic potential of aqueous extracts of two soils (leachates) and of bottom ash resulting from municipal solid waste ...

Very Large Telescope Observations of Interstellar Comet 3I/ATLAS. II. From Quiescence to Glow: Dramatic Rise of Ni i Emission and Incipient CN Outgassing at Large Heliocentric Distances

The Astrophysical Journal Letters
We report Very Large Telescope spectroscopy of the interstellar comet 3I/Asteroid Terrestrial-impact Last Alert System (C/2025 N1), from r _h  ≃ 4.4 to 2.85 au, using X-Shooter (300–550 nm, R  ≃ 3000) and the Ultraviolet and Visual Echelle Spectrograph ...

The effect of the impact of comet Shoemaker Levy‐9 on Jupiter's aurorae [PDF]

, 1995
We present infrared spectra and images of the jovian aurorae taken at wavelengths sensitive to the H-3(+) molecular ion during the period around the impact of Comet Shoemaker Levy-9.

Spectral Characteristics of Interstellar Object 3I/ATLAS from SOAR Observations

The Astrophysical Journal Letters
Interstellar objects (ISOs) provide unique insights into the building blocks and conditions of extrasolar planetary systems. The newly discovered object, 3I/ATLAS (C/2025 N1), represents the third known ISO after 1I/’Oumuamua and 2I/Borisov.

Hubble Space Telescope Observations of the Interstellar Interloper 3I/ATLAS

The Astrophysical Journal Letters
We present high-angular-resolution observations of the third known interstellar interloper, 3I/ATLAS, from the Hubble Space Telescope. The object is clearly active at 3.8 au preperihelion, showing dust emitted from the hot, Sun-facing side of the nucleus

Activity of Halley-type Comets 12P/Pons–Brooks and 13P/Olbers from SOHO/SWAN Observations

The Planetary Science Journal
The Solar Wind ANisotropies (SWAN) all-sky hydrogen Ly α camera on the Solar and Heliosphere Observatory (SOHO) observed the hydrogen coma of Halley-type comet (HTC) 12P/Pons–Brooks from SOHO’s halo orbit around L1 throughout its 2023–2024 apparition ...

Interstellar Object 3I/ATLAS Observed from Mars by China’s Tianwen-1 Spacecraft

The Astrophysical Journal Letters
China’s Tianwen-1 Mars orbiter successfully imaged the third interstellar object, 3I/ATLAS, during its close encounter with Mars using the onboard HiRIC CMOS camera. This is China’s first deep-space observation of an astronomical object.
