Abstract: This work analyzes the detection prospects for weakly interacting massive particles (WIMPs) in dark matter (DM) density spike around the supermassive black hole (SMBH) in Andromeda galaxy M31 in microwave band. WIMP annihilation produces relativistic electrons and positrons, which generate the synchrotron emission in strong magnetic field of the accretion flow medium at microwave frequencies. Properties of this emission, as well as their dependence on DM and medium parameters, were modeled. Atacama Large Millimeter Array (ALMA) sensitivity to this emission and underlying WIMP parameters was estimated. It was obtained that M31* in microwave band represents the unique target, where DM spike signal can be detected in case of realistic spike and halo density profiles. In such case ALMA may reach the thermal s-wave annihilating WIMPs with masses up to around 1 TeV with just 10--100 hours exposure. Optimistic parameter configurations may allow probing all possible WIMP masses up to 100 TeV. Related systematic uncertainties are discussed.

Nepal floods highlight growing glacier risks in warming Himalayas
BENGALURU, India (AP) — Scientists say a deadly flash flood in Nepal on Wednesday was likely caused by a glacier chunk breaking off and temporarily damming a river. This may have led to a surge of water downstream, killing at least 353 people and leaving over 1,300 missing. The U.S. Geological Survey reported a magnitude […]

Let's play a game:
Post the oldest image of your "battle station" / computer setup that you have.
Ideally, post some specs of the system if you can remember.
I'll start:
- photo from 2003
- Pentium II, 350MHz
- 3DFX Voodoo Banshee
- 1024x768 17" Eizo CRT
- Iomega Zip drive, 100MB via Parallel port (*click!*)
- SCSI Scanner hidden away in the background
I think the Mac was a Power Macintosh 6300, but I'm not 100…

Modified Cosmological Expansion and the JWST CMB Optical Depth Tension in Self Interaction Gravity

Abstract: Recent James Webb Space Telescope (JWST) observations favor an earlier and more efficient reionization history, leading to Thomson-scattering optical depths larger than those inferred from the cosmic microwave background (CMB). We investigate whether this tension can be alleviated within the framework of self-interaction (SI) gravity by modifying the cosmological expansion history while retaining the standard astrophysical description of reionization. The SI gravity parameters are constrained through a Bayesian MCMC analysis of the Union3 Type Ia supernova and DESI DR2 Baryon Acoustic Oscillations (BAO) data. The resulting expansion history is then used to predict the ionization history and Thomson optical depth. We find that the predicted optical depth decreases from $\tau_{\rm{CMB}}\simeq0.076$ in $\Lambda$CDM to $\tau_{\rm{CMB}}\simeq0.061$, consistent with the Planck PR4 measurement within $1\sigma$, thereby substantially reducing the optical-depth tension.
