Observations Of Complex Organic Molecules In The Gas Phase Of The Interstellar Medium
Thanks to the advent of sensitive and broad bandwidth instrumentation, complex organic molecules (COMs) have been found in a wide variety of interstellar environments, not only in our Galaxy but […]
![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 […]

Large Interferometer For Exoplanets (LIFE): VIII. Detecting Rocky Exoplanets In The Habitable Zones Of Sun-like Stars
While previous studies have shown a strong preference for a future mid-infrared nulling interferometer space mission to detect habitable zone planets around M-dwarfs, we here focus on a more conservative […]
