论文摘要

由于密度波动的崩溃,原始黑洞(PBHS)可能在早期宇宙中形成。 PBH可以充当最近观察到的一些引力波的来源。我们探索了恒星质量PBH的形成场景,并考虑了QCD相变的可能影响,为此我们考虑了三种不同的模型:交叉模型(CM),BAG模型(BM)和Lattice Fit模型(LFM)。对于波动,我们考虑了一个运行的倾斜幂律频谱。当它们越过$ \ sim 10^{ - 9} $ - $ 10^{ - 1} \ mathrm {〜s} $宇宙界,它们起源于0.05-500〜m $ _ {\ odot} $ pbhs,可以:i)提供了与所有相关的bavection the bardies waver的人群, ii)构成了$ \ sim 76 \%$ $ sim \%$的广泛质量谱,宇宙中所有冷暗物质(CDM)。

Primordial Black Holes (PBHs) might have formed in the early Universe due to the collapse of density fluctuations. PBHs may act as the sources for some of the gravitational waves recently observed. We explored the formation scenarios of PBHs of stellar mass, taking into account the possible influence of the QCD phase transition, for which we considered three different models: Crossover Model (CM), Bag Model (BM), and Lattice Fit Model (LFM). For the fluctuations, we considered a running-tilt power-law spectrum; when these cross the $\sim 10^{-9}$-$10^{-1}\mathrm{~s}$ Universe horizon they originate 0.05-500~M$_{\odot}$ PBHs which could: i) provide a population of stellar mass PBHs similar to the ones present on the binaries associated with all known gravitational wave sources; ii) constitute a broad mass spectrum accounting for $\sim 76\%$ of all Cold Dark Matter (CDM) in the Universe.
