DARWEN: Data-driven Algorithm for Reduction of Wide Exoplanetary Networks
Exoplanet atmospheric modeling is advancing from chemically diverse one-dimensional (1D) models to three-dimensional (3D) global circulation models (GCMs), which are crucial for interpreting observations from facilities like the James Webb […]
![Continuum noise power and FX complex correlator measurements, observed on MJD 60586, are presented together with the statistical power of 3.7 Hz bandwidth, 0.27 s duration polarized pulse pairs, recorded during the 123.8 day experiment. The high correlator response at 5.5 hr RA is due to the Orion A emission nebula at -5.4º DEC. [10][11]. Instrument delay difference of -82 ns between interferometer elements was compensated by choosing to display the -5 x 16 ns correlator tap. The bandwidth of the continuum and correlator measurements is approximately 50 MHz, at 0.27 s integration. The timedependent geometric space delay was not compensated, resulting in the approximate sawtooth phase response across RA, indicating a period of 0.117 hr RA. The prior pointing direction of interest indicates greater than 6 standard deviations Cohen’s d in the 5.1675 ± 0.00375 hr RA bin, within the prior range, 5.25 ± 0.15 hr RA. A second apparent response is indicated in two adjacent bins centered at 8.8425 hr RA, with apparent RA aliasing at ±0.12 hr RA. Figs. 2 and 3 show detail. -- eess.SP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/12/A-Signal-Discovery-Step-In-Interstellar.png?resize=1200%2C719&ssl=1)

A Signal Discovery Step In Interstellar Communication
Prior work using synchronized, geographically spaced radio telescopes, and a radio interferometer, suggests that narrow-bandwidth polarized pulse pair measurements repeatedly falsify a noise-cause hypothesis, given a prior celestial direction of […]
