Low-cost neural summaries for cosmological inference: an ensemble of convolutional neural networks trained on approximate simulations
Iñigo Sáez-Casares, Davide Bianchi, Matteo Calabrese +1
Machine learning can build near-optimal summary statistics for extracting cosmological information from the large-scale structure of the Universe. Training them, however, requires…
TOI-6981 b: a transiting sub-Neptune at the water ice line
Madison G. Scott, Amaury H. M. J Triaud, Emily K. Pass +42
We present TOI-6981 b, a cold (Teq= 170.0 +/-4.5 K, assuming an Earth-like albedo) sub-Neptune (Rb=2.40+/-0.10 R_oplus) on a 60.8 day orbit around around its M4-type host star (R*=…
MIRA: a data management and education platform connecting students to robotic telescopes
Peter P. Pedersen, Lionel Garcia, Mahshid Alimi +3
Hands-on telescope experience is often used to drive student engagement in astronomy education, but scaling access to larger groups of students is operationally challenging. Conseq…
DUET: Design of a simultaneous InGaAs--CCD split-beam imager for ultra-cool dwarf exoplanet transit survey
Peter P. Pedersen, Clark Baker, Karolina Dziewiecka +4
We present the design of DUET, a dual-channel imager being built for the SPECULOOS-Southern Observatory (SSO) to detect and characterise transiting terrestrial exoplanets orbiting…
Astra: an open-source fully autonomous robotic observatory control software
Peter P. Pedersen, David Degen, Lionel Garcia +12
Robotic and autonomous observatories are critical for modern time-domain and high-cadence astronomical surveys. The operation of these facilities requires complex software coordina…
A Previously Underexplored Regime in TESS: Minute-Scale Eclipses Reveal Ten White Dwarf-Cool M-Dwarf Binaries
Tristan Cavalier, Julien de Wit, Mathilde Timmermans +14
Short-period white-dwarf (WD) binaries are post-common-envelope systems that constrain orbital shrinkage, envelope evolution, and the survival of low-mass companions. We report the…
