Title |
Multihorizon regular black holes | |||||
Co-authors | ||||||||
Abstract |
We discuss a general procedure to generate a class of (everywhere regular) solutions of Einstein equations that can have an (a-priori fixed) arbitrary number of horizons. We then report on work currently in progress i) to find a suitable classification scheme for the maximal extension of these solutions and ii) to interpret the source term in Einstein equations as an effective contribution arising from higher dimensional and/or modified gravity. |

Title |
Best fits of simultaneous blazar spectral energy distributions | |||||
Co-authors | ||||||||
Abstract |
We report about recent progress in the first numerical implementations of spectral energy distribution (SED) fits to estimate synchrotron-self Compton (SSC) model parameters. Using two well observed objects, Markarian 421 and Markarian 501, we will highlight the strength of the method, as well as plans for future improvements. |

Title |
Enhanced tunnelling models for child universe formation | |||||
Co-authors | ||||||||
Abstract |
Starting from a recently proposed model that allows for an enhanced rate of child universe production under generic conditions, we elaborate on refinements that may allow for non-singular initial configurations. A possibility to treat both, the initial state and the tunnelling, also beyond the semiclassical level will also be discussed. |
