Detection of Black Holes01:10

Detection of Black Holes

2.2K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Lampbrush Chromosomes

7.9K
In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...

Summary

We found that low-energy hadronic loops can create an effective dark matter-photon coupling. This allows for dark matter-electron scattering detection, even for very light dark matter particles below 100 MeV.

Area of Science:

  • Particle physics
  • Astrophysics
  • Cosmology

Background:

  • Dark matter typically does not interact with photons at tree level.
  • Loop-level interactions are usually ignored in direct detection searches.
  • Detecting low-mass dark matter (<100 MeV) via nuclear recoils is challenging due to low momentum.

Purpose of the Study:

  • To investigate the possibility of an effective dark matter-photon coupling through hadronic loops.
  • To explore dark matter-electron scattering as a detection channel for light dark matter.
  • To establish constraints on light dark matter interactions with protons.

Main Methods:

  • Analyzing loop-level contributions of low-energy hadronic states.
  • Calculating the effective dark matter-photon coupling.
  • Investigating dark matter-electron scattering cross-sections.
  • Constraining interactions using astrophysical observations.

Main Results:

  • Low-energy hadronic loops can induce an effective dark matter-photon coupling.
  • This coupling enables dark matter-electron scattering even without tree-level interactions.
  • Light mediators result in an effective fractional electric charge, strongly constrained by observations.
  • This mechanism allows setting limits on dark matter-proton interactions down to 1 MeV.

Conclusions:

  • Hadronic loops provide a viable mechanism for detecting light dark matter.
  • Dark matter-electron scattering searches offer new avenues for probing low-mass dark matter.
  • Astrophysical constraints significantly limit the parameter space for light dark matter with effective charges.
