Probing galaxy evolution in massive clusters using ACT and DES: splashback as a cosmic clock

Kavli Affiliate: Eli Rykoff | First 5 Authors: Susmita Adhikari, Tae-hyeon Shin, Bhuvnesh Jain, Matt Hilton, Eric Baxter | Summary: We measure the projected number density profiles of galaxies and the splashback feature in clusters selected by the Sunyaev–Zeldovich (SZ) effect from the Advanced Atacama Cosmology Telescope (AdvACT) survey using galaxies observed by the Dark […]

Cosmology Intertwined IV: The Age of the Universe and its Curvature

Kavli Affiliate: Wendy Freedman | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in discriminating between different […]

Cosmology Intertwined III: $f σ_8$ and $S_8$

Kavli Affiliate: Daniel Holz | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The standard $Lambda$ Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with the latest data analyses. While these anomalies […]

Cosmology Intertwined II: The Hubble Constant Tension

Kavli Affiliate: Daniel Holz | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The current cosmological probes have provided a fantastic confirmation of the standard $Lambda$ Cold Dark Matter cosmological model, that has been constrained with unprecedented accuracy. However, with the increase of the experimental sensitivity […]

Cosmology Intertwined I: Perspectives for the Next Decade

Kavli Affiliate: Wendy Freedman | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The standard $Lambda$ Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open questions, that make the standard […]

Mapping the Galactic disk with the LAMOST and $Gaia$ Red clump sample: V: On the origin of the “young” [$α$/Fe]-enhanced stars

Kavli Affiliate: Huawei Zhang | First 5 Authors: Weixiang Sun, Yang Huang, Haifeng Wang, Chun Wang, Meng Zhang | Summary: Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and $Gaia$ surveys, we have identified a large sample of "young" [$alpha$/Fe]-enhanced stars with stellar ages younger than 6.0 Gyr and […]

Intermediate Mass Black Hole Formation in compact Young Massive Star Clusters

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem, Mirek Giersz, J. P. Ostriker | Summary: Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with Nbody6++GPU of 10 […]
