Axion lines from nuclear de-excitations in galactic stellar populations / Ning, Orion (UC, Berkeley ; LBL, Berkeley) ; Ray, Anupam (UC, Berkeley) ; Safdi, Benjamin R. (UC, Berkeley ; LBL, Berkeley ; CERN)
We show that mono-energetic axions are produced in abundance through nuclear de-excitations in nearby galaxies such as M87, which is the central galaxy of the Virgo cluster, and the starburst galaxy M82. [...]

Wino and Real Minimal Dark Matter Excluded by Fermi Gamma-Ray Observations / Safdi, Benjamin R. (UC, Berkeley ; LBL, Berkeley ; CERN) ; Xu, Weishuang Linda (KIPAC, Menlo Park ; SLAC)
We show that minimal, fermionic dark matter (DM) models in the $n$-dimensional representation of the weak force with zero hypercharge that make up 100% of the DM under the standard cosmological history are strongly excluded for $n < 9$. [...]

Discovering the Higgsino at CTAO-North within the Decade / Abe, Shotaro (Tokyo U., ICRR) ; Inada, Tomohiro (Tokyo U., ICRR ; Kyushu U., Fukuoka (main) ; CERN) ; Moulin, Emmanuel (IRFU, Saclay) ; Rodd, Nicholas L. (UC, Berkeley ; LBL, Berkeley) ; Safdi, Benjamin R. (UC, Berkeley ; LBL, Berkeley) ; Xu, Weishuang Linda (UC, Berkeley ; LBL, Berkeley ; KIPAC, Menlo Park ; SLAC)
We demonstrate that higgsino dark matter (DM) could be discovered within the next few years using the Cherenkov Telescope Array Observatory's soon-to-be-operational northern site (CTAO-North). [...]

(MIT, LNS) ; Vital, Inoela (MIT, LNS) ; Winslow, Lindley (MIT, LNS) ; Domcke, Valerie (CERN) ; Lee, Sung Mook (CERN) et al.
ABRACADABRA-10 cm has had great success as a pathfinder lumped-element axion dark matter experiment, setting limits on axion dark matter at the GUT scale. [...]

Resurrecting Hitomi for Decaying Dark Matter and Forecasting Leading Sensitivity for XRISM / Dessert, Christopher (New York U., CCPP ; Flatiron Inst., New York) ; Ning, Orion (UC, Berkeley ; LBL, Berkeley) ; Rodd, Nicholas L. (CERN) ; Safdi, Benjamin R. (UC, Berkeley ; LBL, Berkeley)
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 narrow X-ray lines arising from DM decays. Unfortunately, the satellite was lost shortly after launch, and to-date the only analysis using Hitomi for DM decay used data taken towards the Perseus cluster. [...]

Probing ALPs at the CERN Gamma Factory / Balkin, Reuven (Technion) ; Krasny, Mieczyslaw W. (Paris U., VI-VII ; CERN) ; Ma, Teng (Technion) ; Safdi, Benjamin R. (UC, Berkeley ; LBNL, Berkeley) ; Soreq, Yotam (Technion)
The aim of the proposed CERN Gamma Factory is to produce $\sim 10^{17}$ photons per second with energies up to 400 MeV. The photon beam intensity is expected to be a factor of $\mathcal{O}(10^7)$ larger than that of the presently available photon beams in the MeV energy range. [...]
