Infalling Ultra Faint Dwarfs as Emissaries of the Axiverse?
Recent discoveries of Ultra Faint dwarf galaxies (UFG's) infalling onto the Milky Way, namely Leo K \& M at $r \simeq 450$kpc, considerably strengthens the case that UFG's constitute a distinct galaxy class that is inherently smaller, fainter and metal poor compared to the classical dwarf spheroidals (dSph). This distinction is at odds with the inherent continuity of galaxy halo masses formed under scale-free gravity for any standard dark matter model. Here we show that distinct galaxy classes …

Pure maps are strict monomorphisms
We prove that $i)$ if $\mathcal{A}$ is $λ$-accessible and it is axiomatizable in (finitary) coherent logic then $λ$-pure maps are strict monomorphisms and $ii)$ if there is a proper class of strongly compact cardinals and $\mathcal{A}$ is $λ$-accessible then for some $μ\vartriangleright λ$ every $μ$-pure map is a strict monomorphism.
