: A Fast Memory-based Emulator of the Global 21 cm Signal with Unprecedented Accuracy
J. Dorigo Jones, S. M. Bahauddin, D. Rapetti +2
Neural network (NN) emulators of the global 21 cm signal need emulation error much less than the observational noise in order to be used to perform unbiased Bayesian parameter infe…
: A New Model for Emulating Radio Antenna Beam Patterns for 21-cm Cosmology and Antenna Design Studies
Joshua J. Hibbard, Bang D. Nhan, David Rapetti +1
In 21-cm experimental cosmology, accurate characterization of a radio telescope's antenna beam response is essential to measure the 21-cm signal. Computational electromagnetic (CEM…
Single-Star Warm-Jupiter Systems Tend to Be Aligned, Even Around Hot Stellar Hosts: No Dependency
Xian-Yu Wang, Malena Rice, Songhu Wang +22
The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters' tidal detachment likely pre…
TOI-2490b- The most eccentric brown dwarf transiting in the brown dwarf desert
Beth A. Henderson, Sarah L. Casewell, Andrés Jordán +40
We report the discovery of the most eccentric transiting brown dwarf in the brown dwarf desert, TOI02490b. The brown dwarf desert is the lack of brown dwarfs around main sequence s…
The CARMENES search for exoplanets around M dwarfs. Revisiting the GJ 581 multi-planetary system with new Doppler measurements from CARMENES, HARPS, and HIRES
A. von Stauffenberg, T. Trifonov, A. Quirrenbach +18
GJ 581 is a nearby M dwarf known to host a packed multiple planet system with 2 super-Earths and a Neptune-mass planet. We present new orbital analyses of the system, utilizing rec…
TOI 762 A b and TIC 46432937 b: Two Giant Planets Transiting M Dwarf Stars
Joel D. Hartman, Daniel Bayliss, Rafael Brahm +33
We present the discovery of TOI 762 A b and TIC 46432937 b, two giant planets transiting M dwarf stars. Transits of both systems were first detected from observations by the NASA T…
