Reliability of Zodiacal Background Models at Small Solar Elongations
Csaba Kiss, Thomas G. Müller, Javier Licandro +6
Present models of the zodiacal light (scattered sunlight from interplanetary dust in the visible) and zodiacal emission (thermal emission in the mid-infrared) are primarily constra…
Astrometric follow-up of near-Earth asteroid 2024 YR4 during a Torino scale level 3 alert
Marco Micheli, Maxime Devogèle, Larry Denneau +38
The discovery of 2024 YR4 presented the planetary defense community with the most significant impact threat in almost two decades, reaching level 3 on the Torino scale. The communi…
Rapid-response characterization of near-Earth asteroid 2024 YR4 during a Torino Scale 3 alert
Maxime Devogèle, Olivier R. Hainaut, Marco Micheli +32
On 27 December 2024, near-Earth object (NEO) 2024 YR was discovered by the ATLAS survey and identified as a virtual impactor. A few weeks later, it eventually reached level 3 o…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
Darryl Z. Seligman, Marco Micheli, Davide Farnocchia +44
We report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an…
Astrometry, orbit determination, and thermal inertia of the Tianwen-2 target asteroid (469219) Kamo`oalewa
Marco Fenucci, Bojan Novaković, Pengfei Zhang +9
Context. (469219) Kamo`oalewa is a small near-Earth asteroid, which is currently a quasi-satellite of the Earth. Lightcurve measurements also reveal a rotation period of only about…
The fall of asteroid 2024 XA and the location of possible meteorites
Francesco Gianotto, Albino Carbognani, Marco Fenucci +18
Asteroid 2024 XA was discovered on 3 December 2024 at 05:54 UTC by the Bok telescope in Kitt Peak, Arizona, and impacted Earth about 10 hours later over a remote area of the Sa…
Site Selection for the Second Flyeye Telescope: A Simulation Study for Optimizing Near-Earth Object Discovery
D. Föhring, L. Conversi, M. Micheli +2
The European Space Agency (ESA) is developing a network of wide-field survey telescopes, named Flyeye, to improve the discovery of Near-Earth Objects (NEOs). The first telescope in…
Aperture photometry on asteroid trails: detection of the fastest rotating near-Earth object
Maxime Devogèle, Luca Buzzi, Marco Micheli +9
Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speed. Understanding their properties, including rotation state, is crucial for assessing…
An automated procedure for the detection of the Yarkovsky effect and results from the ESA NEO Coordination Centre
Marco Fenucci, Marco Micheli, Francesco Gianotto +7
Context: The measurement of the Yarkovsky effect on near-Earth asteroids (NEAs) is common practice in orbit determination today, and the number of detections will increase with the…
Mining archival data from wide-field astronomical surveys in search of near-Earth objects
Teymoor Saifollahi, Gijs Verdoes Kleijn, Rees Williams +5
Increasing our knowledge of the orbits and compositions of Near-Earth Objects (NEOs) is important for a better understanding of the evolution of the Solar System and of life. The d…
The starburst-AGN connection in the merger galaxy Mrk 938: an infrared and X-ray view
P. Esquej, A. Alonso-Herrero, A. M. Pérez-García +14
Mrk938 is a luminous infrared galaxy in the local Universe believed to be the remnant of a galaxy merger. It shows a Seyfert 2 nucleus and intense star formation according to optic…
Measures of star formation rates from Infrared (Herschel) and UV (GALEX) emissions of galaxies in the HerMES fields
V. Buat, E. Giovannoli, D. Burgarella +75
The reliability of infrared (IR) and ultraviolet (UV) emissions to measure star formation rates in galaxies is investigated for a large sample of galaxies observed with the SPIRE a…
