A Tension between recent dark matter results and Lux-Xenon?

AI Thread Summary
Recent discussions highlight a potential conflict between the AMS-02 findings of an 80 GeV WIMP dark matter particle and the negative results from the LUX and Xenon experiments. The existence of this particle raises questions about why it hasn't been detected in these experiments, leading to speculation about its visibility in future tests like the LZ experiment. Skepticism exists regarding the interpretation of the AMS-02 signal, particularly its compatibility with gamma-ray emissions from pulsars, which could explain similar observations. The tension between these results underscores the complexity of dark matter research and the need for further investigation. Continued exploration in upcoming experiments may clarify these discrepancies.

How much tension between recent AMS-02 80 Gev dark matter and Lux-Xenon negative results?
Recent results ( Arxiv 1610.03840 and 1704.08258) suggest a WIMP dark matter particle near 80 Gev. See also https://phys.org/news/2017-05-possibility-cosmic-rays-due-dark.html

If this particle really exists, should we have seen it in recent negative results from Lux and Xenon?

Should we see it in forthcoming LZ experiment?

I'm not sure how this claim ties back to the LUX data, but I'm always leery of claims like this:

From the abstract: Intriguingly, this signal is compatible with the DM interpretation of the Galactic center gamma-ray excess.

For quite some time it's been known that pulsars could emit the same type of gamma signals from the core, so I take these types of claims with grain of salt, particularly when they assign a 4.3 sigma to the claim. :) I'd assume that they simply didn't try a 'model' with a lot of large pulsars near the core. :)
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
