Abstract In Adamović (Commun Math Phys 366:1025–1067, 2019), the affine vertex algebra $$L_k({{\mathfrak {s}}}{{\mathfrak {l}}}_2)$$ L k ( s l 2 ) is realized as ...

We undertook a search for new dwarf galaxies in the Leo-I group using data from DECaLS digital sky survey. Five presumed members of this have been found wide vicinity ${\rm M}\,105 ({\rm NGC}\,3379$). Currently, has population $83$ galaxies, $33$ which measured radial velocities. More than half belong to early types with no signs ongoing star formation. About quarter are outside group's virial ...

Rapid advance has been made recently in accurate distance measurements for nearby ($D < 11$ Mpc) galaxies based on the magnitude of tip red giant branch stars resolved with Hubble Space Telescope. We use observational properties presented last version Updated Nearby Galaxy Catalog to derive a halo mass luminous via orbital motion their companions. Our sample contains 298 assumed satellites know...

The vertex algebras $$\mathcal {V}^{(p)}$$ and R^{(p)}$$ introduced in Adamovi? (Transform Groups 21(2):299–327, 2016) are very interesting relatives of the well-known triplet logarithmic CFT. algebra (respectively, {R}^{(p)}$$ ) is a large extension simple affine $$L_{k}(\mathfrak {sl}_{2})$$ times Heisenberg algebra), at level $$k=-2+1/p$$ for positive integer p. Particularly, {V}^{(2)}$$ sma...
