Was There a 3.5 keV Line?

Christopher Dessert, Joshua W. Foster, Yujin Park +1

The 3.5 keV line is a purported emission line observed in galaxies, galaxy clusters, and the Milky Way whose origin is inconsistent with known atomic transitions and has previously…

Limits from the grave: resurrecting Hitomi for decaying dark matter and forecasting leading sensitivity for XRISM

Christopher Dessert, Orion Ning, Nicholas L. Rodd +1

The Hitomi X-ray satellite mission carried unique high-resolution spectrometers that were set to revolutionize the search for sterile neutrino dark matter (DM) by looking for narro…

A deep search for decaying dark matter with XMM-Newton blank-sky observations

Joshua W. Foster, Marius Kongsore, Christopher Dessert +4

Sterile neutrinos with masses in the keV range are well-motivated extensions to the Standard Model that could explain the observed neutrino masses while also making up the dark mat…

Technical comment on the paper of Dessert et al. "The dark matter interpretation of the 3.5 keV line is inconsistent with blank-sky observations"

Alexey Boyarsky, Denys Malyshev, Oleg Ruchayskiy +1

An unidentified line at energy around 3.5 keV was detected in the spectra of dark matter-dominated objects. Recent work of Dessert et al. [1812.06976] used 30 Msec of XMM-Newton bl…

The dark matter interpretation of the 3.5-keV line is inconsistent with blank-sky observations

Christopher Dessert, Nicholas L. Rodd, Benjamin R. Safdi

Observations of nearby galaxies and galaxy clusters have reported an unexpected X-ray emission line around 3.5 kilo-electron volts (keV). Proposals to explain this line include dec…
