Tomography of the gamma-ray sky from cross-correlation with DESI DR2 and unWISE galaxies
Alex Krolewski, Neal Dalal, Will J. Percival +39
We study the origin of extragalactic gamma-ray emission observed by Fermi-LAT, using the cross-correlation of the gamma-ray sky with maps of large-scale structure provided by the D…
The Tianlai-WIYN North Celestial Cap Redshift Survey
Reza Ansari, Gabriela A. Marques, John P. Marriner +13
We present the results of a small, low redshift spectroscopic survey of galaxies within 3 degrees of the North Celestial Pole (NCP) selected using V-band photometry obtained from t…
The Impact of Muon and Pion Cooling on the Neutrino Spectrum of NGC 1068
Carlos Blanco, Dan Hooper, Tim Linden +1
The IceCube Neutrino Observatory has detected a flux of neutrinos from the active galaxy, NGC 1068. The soft spectral index of these neutrinos has previous…
Dark Matter and Galaxy Cross-Correlations with the Cherenkov Telescope Array Observatory
Elena Pinetti, Veronika Vodeb, Aurelio Amerio +4
The Cherenkov Telescope Array Observatory (CTAO) will be a ground-based Cherenkov telescope performing wide-sky surveys, ideal for anisotropy studies such as cross-correlations wit…
Dark matter decay signals in cosmic filaments
Elena Pinetti, Evan Vienneau, Nassim Bozorgnia
Cosmic filaments form the backbone of the cosmic web, yet their properties and evolution remain uncertain. Using the EAGLE hydrodynamical simulations, we investigate the dark matte…
Observing Dark Matter Decays to Gravitons via Graviton-Photon Conversion
David I. Dunsky, Gordan Krnjaic, Elena Pinetti
Since dark matter is only known to have gravitational interactions, it may plausibly decay to gravitons on cosmological timescales. Although such a scenario can be easily realized,…
First constraints on QCD axion dark matter using James Webb Space Telescope observations
Elena Pinetti
We present the first constraints on QCD axion dark matter using measurements from the James Webb Space Telescope. By utilizing publicly available MIRI and NIRSpec blank-sky observa…
Cross Correlating the Unresolved Gamma-Ray Background with Cosmic Large-Scale Structure from DESI: Implications for Astrophysics and Dark Matter
Bei Zhou, José Luis Bernal, Elena Pinetti +2
The unresolved gamma-ray background (UGRB) is a diffuse gamma-ray emission arising from numerous extragalactic sources below the detection threshold and is an important component o…
Searching for Synchrotron Emission from the Geminga TeV Halo using the Planck Satellite
Dan Hooper, Elena Pinetti, Anastasia Sokolenko
Pulsars convert a significant fraction of their total spin-down power into very high-energy electrons, leading to the formation of TeV halos. It is not yet known, however, whether…
Unraveling TeV Halos with the Cherenkov Telescope Array
Dan Hooper, Elena Pinetti, Anastasia Sokolenko
Pulsars are observed to emit bright and spatially extended emission at multi-TeV energies. Although such "TeV halos" appear to be an approximately universal feature of middle-aged…
Reviving MeV-GeV Indirect Detection with Inelastic Dark Matter
Asher Berlin, Gordan Krnjaic, Elena Pinetti
Thermal relic dark matter below is excluded by cosmic microwave background data if its annihilation to visible particles is unsuppressed near the epoch of re…
Hunting Dark Matter Lines in the Infrared Background with the James Webb Space Telescope
Ryan Janish, Elena Pinetti
Dark matter particles with a mass around 1 eV can decay into near-infrared photons. Utilising available public blank sky observations from the NIRSpec IFU on the James Webb Space T…
On the Neutrino and Gamma-Ray Emission from NGC 1068
Carlos Blanco, Dan Hooper, Tim Linden +1
IceCube has recently reported the detection of neutrinos from the nearby active galaxy, NGC 1068. The lack of TeV-scale emission from this source suggests t…
Probing The Longest Dark Matter Lifetimes with the Line Emission Mapper
Gordan Krnjaic, Elena Pinetti
In the next decade, the proposed Line Emission Mapper (LEM) telescope concept is poised to revolutionize Galactic and extragalactic X-ray sensitivity. The instruments aboard LEM fe…
Putting all the X in one basket: Updated X-ray constraints on sub-GeV Dark Matter
Marco Cirelli, Nicolao Fornengo, Jordan Koechler +2
Sub-GeV dark matter particles can annihilate or decay producing e^\pm pairs which upscatter the low-energy photon fields in the Galaxy and generate an X-ray emission (via the Inver…
From gamma rays to radio waves: Dark Matter searches across the spectrum
Elena Pinetti
In this thesis, we examined the possibilities offered by multi-messenger astronomy in the context of indirect dark matter detection. We have applied a multi-wavelength strategy by…
The Second Radio Synchrotron Background Workshop: Conference Summary and Report
J. Singal, N. Fornengo, M. Regis +24
We summarize the second radio synchrotron background workshop, which took place June 15-17, 2022 in Barolo, Italy. This meeting was convened because available measurements of the d…
Got plenty of nothing: cosmic voids as a probe of particle dark matter
S. Arcari, E. Pinetti, N. Fornengo
The search for a particle dark matter signal in terms of radiation produced by dark matter annihilation or decay has to cope with the extreme faintness of the predicted signal and…
Flat spectrum radio quasars and BL Lacs dominate the anisotropy of the unresolved gamma-ray background
Michael Korsmeier, Elena Pinetti, Michela Negro +2
We analyze the angular power spectrum (APS) of the unresolved gamma-ray background (UGRB) emission and combine it with the measured properties of the resolved gamma-ray sources of…
The cosmic coincidences of primordial-black-hole dark matter
Yi-Peng Wu, Elena Pinetti, Joseph Silk
If primordial black holes (PBHs) contribute more than 10 percent of the dark matter (DM) density, their energy density today is of the same order as that of the baryons. Such a cos…
Baryogenesis from ultra-slow-roll inflation
