Kavli Affiliate: Risa Wechsler | First 5 Authors: Monica Valluri, Solene Chabanier, Vid Irsic, Eric Armengaud, Michael Walther | Summary: Despite efforts over several decades, direct-detection experiments have not yet led to the discovery of the dark matter (DM) particle. This has led to increasing interest in alternatives to the Lambda CDM (LCDM) paradigm and […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Rogério Riffel, Luis G. Dahmer-Hahn, Rogemar A. Riffel, Thaisa Storchi-Bergmann, Natacha Z. Dametto | Summary: We use Gemini Near-Infrared Integral Field Spectrograph (NIFS) adaptive optics assisted data-cubes to map the stellar population of the inner few hundred parsecs of a sample of 18 nearby Seyfert galaxies. The […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Kristi Engel, Jordan Goodman, Petra Huentemeyer, Carolyn Kierans, Tiffany R. Lewis | Summary: Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about particle acceleration in environments so extreme they cannot be […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine, Katelin Schutz, Susmita Adhikari | Summary: The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, and spins of these halos can be tied to the underlying fundamental […]
Kavli Affiliate: Salman Habib, Katrin Heitmann | First 5 Authors: Marcelo A. Alvarez, Arka Banerjee, Simon Birrer, Salman Habib, Katrin Heitmann | Summary: Powerful new observational facilities will come online over the next decade, enabling a number of discovery opportunities in the “Cosmic Frontier”, which targets understanding of the physics of the early universe, dark […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Prajwal Niraula, Avi Shporer, Ian Wong, Julien de Wit, | Summary: Space-based photometric missions widely use statistical validation tools for vetting transiting planetary candidates, particularly when other traditional methods of planet confirmation are unviable. In this paper, we refute the planetary nature of three previously validated planets […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Kyle Dawson, Andrew Hearin, Katrin Heitmann, Mustapha Ishak, Johannes Ulf Lange | Summary: Joint studies of imaging and spectroscopic samples, informed by theory and simulations, offer the potential for comprehensive tests of the cosmological model over redshifts z<1.5. Spectroscopic galaxy samples at these redshifts can be increased […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Jorge De Blas, Dario Buttazzo, Rodolfo Capdevilla, David Curtin, Roberto Franceschini | Summary: In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. Reviewing the physics potential of such muon […]
Kavli Affiliate: Liantao Wang | First 5 Authors: Chiara Aimè, Aram Apyan, Mohammed Attia Mahmoud, Nazar Bartosik, Alessandro Bertolin | Summary: The perspective of designing muon colliders with high energy and luminosity, which is being investigated by the International Muon Collider Collaboration, has triggered a growing interest in their physics reach. We present a concise […]
