Extracting cosmological information from the abundance of galaxy clusters with simulation-based inference

Posted by dbos Cambridge

Kavli Affiliate: Anthony Challinor | First 5 Authors: Íñigo Zubeldia, Boris Bolliet, Anthony Challinor, William Handley, | Summary: The abundance of galaxy clusters as a function of mass and redshift is a well-established and powerful cosmological probe. Cosmological analyses based on galaxy cluster number counts have traditionally relied on explicitly computed likelihoods, which are often […]

The X-ray statistical properties of dust-obscured galaxies detected by eROSITA

Posted by dbos Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Akatoki Noboriguchi, Kohei Ichikawa, Yoshiki Toba, Tom Dwelly, Kohei Inayoshi | Summary: Dust-obscured galaxies (DOGs) are considered to be in a co-evolution phase, with the associated active galactic nuclei (AGN) obscured by dust and gas. Although the DOGs are thought to harbor rapidly growing SMBHs, their X-ray […]

Sample Efficient Algorithms for Linear System Identification under Noisy Observations

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Yuyang Zhang, Xinhe Zhang, Jia Liu, Na Li, | Summary: In this paper, we focus on learning linear dynamical systems under noisy observations. In this setting, existing algorithms either yield biased parameter estimates, or suffer from large sample complexities. To address these issues, we adapt the instrumental […]

The Effect of Nonlinear Gravity on the Cosmological Background During Preheating

Posted by Chicago

Kavli Affiliate: Joshua Frieman | First 5 Authors: Ryn Grutkoski, Hayley J. Macpherson, John T. Giblin Jr, Joshua Frieman, | Summary: We use numerical relativity to study the violent preheating era at the end of inflation. This epoch can result in highly nonlinear fluctuations in density and gravitational potential which feed back onto the averaged […]
