• Euclid preparation : XVII. Cosmic Dawn Survey : Spitzer Space Telescope observations of the Euclid deep fields and calibration fields 

  Euclid Collaboration (EDP Sciences, 2022)

  We present a new infrared survey covering the three Euclid deep fields and four other Euclid calibration fields using Spitzer Space Telescope’s Infrared Array Camera (IRAC). We combined these new observations with all ...

• Systematic moment expansion for electroweak baryogenesis 

  Kainulainen, Kimmo; Venkatesan, Niyati (IOP Publishing, 2024)

  We present a systematic moment expansion for solving the semiclassical Boltzmann equations for electroweak baryogenesis. The expansion is developed in powers of adiabatic coordinate velocity, and it is used for computing ...

• The first-order evolution of cosmic scalar perturbations 

  Aalto, Tuomas (2019)

  Nykytietämyksen mukaan kosminen inflaatio jätti pieniä häiriöitä lähes homogeeniseen varhaiseen maailmankaikkeuteen. Nykyään havaittavien kosmisten rakenteiden kehittyminen näistä häiriöistä on yksi kosmologian keskeisistä ...

• Anomaly-free scale symmetry and gravity 

  Shaposhnikov, Mikhail; Tokareva, Anna (Elsevier BV, 2023)

  In this Letter, we address the question of whether the conformal invariance can be considered as a global symmetry of a theory of fundamental interactions. To describe Nature, this theory must contain a mechanism of ...

• Spherically Symmetric Terrestrial Planets with Discontinuities Are Spectrally Rigid 

  Ilmavirta, Joonas; de Hoop, Maarten V.; Katsnelson, Vitaly (Springer, 2024)

  We establish spectral rigidity for spherically symmetric manifolds with boundary and interior interfaces determined by discontinuities in the metric under certain conditions. Rather than a single metric, we allow two ...
