Unified Halo-Independent Formalism Derived From Convex Hulls / Gelmini, Graciela B. (UCLA) ; Huh, Ji-Haeng (CERN) ; Witte, Samuel J. (Valencia U., IFIC ; UCLA)
Using the Fenchel-Eggleston theorem for convex hulls (an extension of the Caratheodory theorem), we prove that any likelihood can be maximized by either a dark matter 1- speed distribution $F(v)$ in Earth's frame or 2- Galactic velocity distribution $f^{\rm gal}(\vec{u})$, consisting of a sum of delta functions. The former case applies only to time-averaged rate measurements and the maximum number of delta functions is $({\mathcal N}-1)$, where ${\mathcal N}$ is the total number of data entries. [...]

Assessing Compatibility of Direct Detection Data: Halo-Independent Global Likelihood Analyses / Gelmini, Graciela B. (UCLA) ; Huh, Ji-Haeng (CERN) ; Witte, Samuel J. (UCLA)
We present two different halo-independent methods utilizing a global maximum likelihood that can assess the compatibility of dark matter direct detection data given a particular dark matter model. The global likelihood we use is comprised of at least one extended likelihood and an arbitrary number of Poisson or Gaussian likelihoods. [...]

Experimental relevance of low reheating temperature cosmologies / Gelmini, Graciela B. (UCLA ; CERN)
Standard simple assumptions are usually made about the pre-Big Bang Nucleosynthesis epoch, from which we do not have observations. Modifying these assumptions, the predicted density of relic particles such as neutralinos and sterile neutrinos can be very different from that in the standard case. [...]

MeV sterile neutrinos in low reheating temperature cosmological scenarios / Gelmini, Graciela (UCLA ; CERN) ; Osoba, Efunwande (UCLA) ; Palomares-Ruiz, Sergio (Durham U., IPPP) ; Pascoli, Silvia (Durham U., IPPP)
It is commonly assumed that the cosmological and astrophysical bounds on the mixings of sterile with active neutrinos are much more stringent than those obtained from laboratory measurements. We point out that in scenarios with a very low reheating temperature T_RH << 100 MeV at the end of (the last episode of) inflation or entropy creation, the abundance of sterile neutrinos becomes largely suppressed with respect to that obtained within the standard framework. [...]

Ultra-cold WIMPs: relics of non-standard pre-BBN cosmologies / Gelmini, Graciela B. (UCLA) ; Gondolo, Paolo (Utah U.)
Weakly interacting massive particles (WIMPs) constitute one of very few probes of cosmology before big bang nucleosynthesis (BBN). We point out that in scenarios in which the Universe evolves in a non-standard manner during and after WIMP kinetic decoupling, the horizon mass scale at decoupling can be smaller and the dark matter WIMPs can be colder than in standard cosmology. [...]

Composition of UHECR and the Pierre Auger Observatory Spectrum / Arisaka, Katsushi (UCLA, Los Angeles, CA, USA) ; Gelmini, Graciela B (UCLA, Los Angeles, CA, USA ; CERN) ; Healy, Matthew (UCLA, Los Angeles, CA, USA) ; Kalashev, Oleg (INR RAS, Moscow, Russia) ; Lee, Joong (UCLA, Los Angeles, CA, USA)
We fit the recently published Pierre Auger ultra-high energy cosmic ray spectrum assuming that either nucleons or nuclei are emitted at the sources. We consider the simplified cases of pure proton, or pure oxygen, or pure iron injection. [...]
