A ready-to-deploy MLOps software platform for satellite and NEO detection at meter-class ground-based observatories
Rafael Carrillo Navarro, Pablo García-Martín, René Duffard +2
Ground-based astronomical observations frequently contain streaks produced by artificial satellites, space debris, and potentially Near-Earth Objects (NEOs). While machine-learning…
StreakMind: AI detection and analysis of satellite streaks in astronomical images with automated database integration
Rafael Carrillo Navarro, René Duffard, Pablo García-Martín +3
Artificial satellites and space debris increasingly contaminate astronomical images, affecting scientific surveys and producing large volumes of streaked exposures. Manual inspecti…
Influence of a magnetic field on the frequency of a laser stabilized to molecular iodine
Jonathan Gillot, Joannes Barbarat, Charles Philippe +3
We report on the effect of a weak magnetic field applied on an iodine cell used to frequency stabilize a laser. A 1.5m laser is frequency tripled in order to excite the molecul…
Geodetic Research on Deception Island and its Environment (South Shetland Islands, Bransfield Sea and Antarctic Peninsula) During Spanish Antarctic Campaigns (1987-2007)
M. Berrocoso, A. Fernández-Ros, M. E. Ramírez +14
Since 1987, Spain has been continuously developing several scientific projects, mainly based on Earth Sciences, in Geodesy, Geochemistry, Geology or Volcanology. The need of a geod…
Near-to mid-IR spectral purity transfer with a tunable frequency comb: methanol frequency metrology over a record frequency span
D B A Tran, Olivier Lopez, M Manceau +8
We report the upgrade and operation of a frequency-comb-assisted high-resolution mid-infrared molecular spectrometer allowing us to combine high spectral purity, SI-traceability, w…
The stellar occultation by (319) Leona on 13 September 2023 in preparation for the occultation of Betelgeuse
J. L. Ortiz, M. Kretlow, C. Schnabel +36
On 12 December 2023, the star Orionis (Betelgeuse) will be occulted by the asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyze the diameter…
Accurate laser frequency locking to optical frequency combs under low-signal-to-noise-ratio conditions
C. Guo, M. Favier, N. Galland +7
We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb in conditions where the signal-to-noise ratio is low, too low t…
A new experiment to test parity symmetry in cold chiral molecules using vibrational spectroscopy
A Cournol, M. Manceau, M. Pierens +21
We present a brief review of our progress towards measuring parity violation in heavy-metal chiral complexes using mid-infrared Ramsey interferometry. We discuss our progress addre…
High-precision methanol spectroscopy with a widely tunable SI-traceable frequency-comb-based mid-infrared QCL
R. Santagata, D. Tran, B. Argence +14
There is an increasing demand for precise molecular spectroscopy, in particular in the mid-infrared fingerprint window that hosts a considerable number of vibrational signatures, w…
Monitoring the Solar Radius from the Royal Observatory of the Spanish Navy during the Last Quarter-Millennium
J. M. Vaquero, M. C. Gallego, J. J. Ruiz-Lorenzo +5
The solar diameter has been monitored at the Royal Observatory of the Spanish Navy (today the Real Instituto y Observatorio de la Armada: ROA) almost continuously since its creatio…
Precision measurement of the neutrino velocity with the ICARUS detector in the CNGS beam
M. Antonello, B. Baibussinov, F. Boffelli +68
During May 2012, the CERN-CNGS neutrino beam has been operated for two weeks for a total of 1.8 10^17 pot in bunched mode, with a 3 ns narrow width proton beam bunches, separated b…
Measurement of CNGS muon neutrino speed with Borexino
Borexino Collaboration
We have measured the speed of muon neutrinos with the Borexino detector using short-bunch CNGS beams. The final result for the difference in time-of-flight between a <E>=17 GeV muo…
Families of Canonical Transformations by Hamilton-Jacobi-Poincaré equation. Application to Rotational and Orbital Motion
Sebastián Ferrer, Martin Lara
The Hamilton-Jacobi equation in the sense of Poincaré, i.e. formulated in the extended phase space and including regularization, is revisited building canonical transformations wit…
The Calar Alto lunar occultation program: update and new results
A. Richichi, O. Fors, M. Merino +6
We present an update of the lunar occultation program which is routinely carried out in the near-IR at the Calar Alto Observatory. A total of 350 events were recorded since our las…
On the constraining observations of the dark GRB 001109 and the properties of a z = 0.398 radio selected starburst galaxy contained in its error box
J. M. Castro Cerón, J. Gorosabel, A. J. Castro-Tirado +24
We present optical and NIR (near infrared) follow up observations of the GRB 001109 from 1 to 300 days after the burst. No transient emission was found at these wavelengths within…
GRB 011121: A collimated outflow into wind-blown surroundings
J. Greiner, S. Klose, M. Salvato +31
We discover a break in the GRB 011121 afterglow light curve after 1.3 days, which implies an initial jet opening angle of about 9 deg. The SED during the first four days is achroma…
