seminar Yann Gouttenoire Tuesday 27 June at 14:00
by Alberto Mariotti 26 Jun '23

26 Jun '23

Dear All, I'm happy to announce the seminar of Yann Gouttenoire (Tel Aviv University) next week Tuesday 27 June at 14:00 in the room G.1.03 - J. Sacton (Building G) at IIHE. Here the webpage of the event: https://indico.iihe.ac.be/event/1797/ Yann will talk about: Title: Primordial black holes from supercooled phase transition and implications for Pulsar Timing Arrays Abstract: Cosmological first-order phase transitions are said to be supercooled when the nucleation temperature is much smaller than the critical temperature. They are typical of potentials which feature nearly scale-invariance, for which the bounce action decreases only logarithmically with time. The phase transition takes place slowly and the probability distribution of bubble nucleation time is maximally spread. Hubble patches which get percolated later than the average are hotter than the background after reheating and potentially collapse into primordial black holes (PBH). In the first part of the talk, I will discuss the formation of PBH by supercooled phase transitions. In the second part, I will discuss the search for supercooled phase transitions in pulsar timing arrays and how it affects the search for PBH in LIGO-Virgo. Yann will be visiting us from Tuesday to Friday, so there will be plenty of time for discussions.

JC Friday 12th 2 pm
by Miguel Vanvlasselaer 11 May '23

11 May '23

Hello everyone, next JC this Friday (exceptional date) at 2pm. Martina will talk about non-thermal leptogenesis and her master project. Abstract: In this talk, we intend to provide an alternative path to the standard thermal leptogenesis mainly studied in the literature, focusing on the possibility to source non-thermal leptogenesis via decays of ALPs. We estimate the contribution of this non-thermal ALP leptogenesis and compute it by solving the associated Boltzmann equations, assuming that the species involved are in kinetic equilibrium. The advantages of this alternative approach are that, while standard leptogenesis would undergo strong washout at the temperatures of interest for our mechanism, our non-thermal leptogenesis via ALP decays avoids this, and the secondary non-thermal population of $N$, produced via ALP decays, would fuel leptogenesis, enhancing the resulting baryon asymmetry. I hope to see you there, Best, Miguel

Hello everyone, next JC on tuesday 18 2pm. Xander will talk about the GREA model and discuss https://arxiv.org/abs/2106.16012, https://arxiv.org/abs/2111.13083 and https://arxiv.org/abs/2302.08537 [https://static.arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png]<https://arxiv.org/abs/2111.13083> A GREAT model comparison against the cosmological constant<https://arxiv.org/abs/2111.13083> Recently, a covariant formulation of non-equilibrium phenomena in the context of General Relativity was proposed in order to explain from first principles the observed accelerated expansion of the Universe, without the need for a cosmological constant, leading to the GREA theory. Here, we confront the GREA theory against the latest cosmological data, including type Ia supernovae, baryon acoustic oscillations, the cosmic microwave background (CMB) radiation, Hubble rate data from the cosmic chronometers and the recent $H_0$ measurements. We perform Markov Chain Monte Carlo analyses and a Bayesian model comparison, by estimating the evidence via thermodynamic integration, and find that when all the aforementioned data are included, but no prior on $H_0$, the difference in the log-evidence is $\\sim -9$ in favor of GREA, thus resulting in overwhelming support for the latter over the cosmological constant and cold dark matter model ($Λ$CDM). When we also include priors on $H_0$, either from Cepheids or the Tip o arxiv.org [https://static.arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png]<https://arxiv.org/abs/2106.16012> Covariant formulation of non-equilibrium thermodynamics in General Relativity<https://arxiv.org/abs/2106.16012> arxiv.org [https://static.arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png]<https://arxiv.org/abs/2302.08537> The effect of GREA on the gravitational collapse of neutron stars<https://arxiv.org/abs/2302.08537> General Relativistic Entropic Acceleration (GREA) gives a general framework in which to study multiple out-of-equilibrium phenomena in the context of general relativity, like the late accelerated expansion of the universe or the formation of galaxies and the large scale structure of the universe. Here we analyze the conditions for collapse of a star of degenerate neutrons in the presence of entropy production due to the gravitational collapse itself. We find that the final mass and radius of the neutron star differs from that obtained with the adiabatic Tolman-Oppenheimer-Volkoff equation by a factor of order 15\\%. We also find that the minimum mass of a neutron star is $\\sim 1.1\\,M_\\odot$ and the maximum mass around $2.4\\,M_\\odot$. We discuss the possible implications for the search and interpretation of binary coalescing systems like neutron stars and neutron star-black holes detectable via their multimessenger (gravitational and electromagnetic wave) emission upon merging. arxiv.org I hope to see you there, Best, Miguel

Dear All, here a list of confirmed visitors/speakers that will visit our group in the coming period. Oriol Pujolas (from IFAE). He will come one-day, giving a talk, on the 27 of April. Unfortunately he can be present only on that day for family reasons. He works on DW and many aspects of GW related to our interests, so I encourage you to be present on that day. Diego Redigolo (Firenze University). He will visit jointly VUB and ULB from 22 to 26 May. Diego is a long-term collaborator of mine about pheno aspects of SUSY. He is working now on cosmological perturbations, and he will give a talk on such topic on Thursday or Friday of that week. Yann Gouttenoire (Tel Aviv University). He will visit us from 26 to 30 June. He is an expert on phase transitions and cosmic strings. He will present us his work on Monday or Tuesday of that week (still to be defined).

Hello everyone, Next JC on monday 27, 2pm. We start our series on baryogenesis with Alberto that will talk about a very recent paper: https://arxiv.org/abs/hep-ph/9810261 on baryogenesis from cosmic string and discuss possible ways to extend it to domain walls. My JC on VIA sources for electroweak baryogenesis is postponed, likely to monday 3/04. Hope to see you there, Best, Miguel

Hello everyone, Next JC on Tuesday 14/03 at 3 pm in J.Lemonne G/1-G.1.12. I (AGAIN!) will talk about https://arxiv.org/pdf/2206.01120.pdf which claims to rule out VIA sources for EWBG and puts now usual EWBG scenario at odds with EDM measurements. Maybe we can try a discussion on alternatives to usual EWBG mechanism. Hope to see you there, Kind regards, Miguel
