When galaxies burst II. Implications of enhanced burstiness for the 21-cm Cosmic Dawn signal

Hovav Lazare, Sarah Libanore, Eleonora Vanzan +2

Recent JWST observations suggest that star formation in the early universe was substantially burstier than assumed in standard models. Such burstiness can be described as a stochas…

When galaxies burst: enhanced shot-noise for line-intensity mapping in the JWST era

Ely D. Kovetz, Hovav Lazare, Sarah Libanore +2

Recent JWST observations indicate that star formation at is more stochastic than previously assumed, with rms log-SFR scatter dex at $M_h\!\sim\!10^{11}M…

Testing the growth of cosmic structures during the Dark Ages

Elena Vanetti, Eleonora Vanzan, Nicola Bellomo +1

Hydrogen 21-cm Line Intensity Mapping offers the unique opportunity to access the Dark Ages and trace the formation and evolution of the large scale structure of the Universe prior…

Searching for blue in the dark

Jessie de Kruijf, Eleonora Vanzan, Kimberly K. Boddy +2

The primordial power spectrum of curvature perturbations has been well-measured on large scales but remains fairly unconstrained at smaller scales, where significant deviations fro…

Observed unequal-time power spectrum

Francesco Spezzati, Eleonora Vanzan, Alvise Raccanelli +2

The next generation of galaxy surveys will provide highly precise measurements of galaxy clustering, therefore requiring a corresponding accuracy. Current approaches, which rely on…
