Quasar lifetime measurements from extended Ly$α$ nebulae at $zsim 6$

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Dominika Ďurovčíková, Anna-Christina Eilers, Romain A. Meyer, Emanuele Paolo Farina, Eduardo Bañados | Summary: The existence of billion-solar-mass black holes hosted in luminous quasars within the first gigayear of cosmic history poses a challenge to our understanding of supermassive black hole (SMBH) growth. The problem is […]

Turning a negative neutrino mass into a positive optical depth

Kavli Affiliate: Wayne Hu | First 5 Authors: Tanisha Jhaveri, Tanvi Karwal, Wayne Hu, , | Summary: Under $Lambda$CDM, recent baryon acoustic oscillation (BAO) distance measures from DESI, which favor a low matter density $Omega_m$, are in moderate $2-3sigma$ tension with cosmic microwave background (CMB) observations. This tension appears alternately as a preference for the […]

The Challenges of Detecting Gases in Exoplanet Atmospheres

Kavli Affiliate: Sara Seager | First 5 Authors: Luis Welbanks, Matthew C. Nixon, Peter McGill, Lana J. Tilke, Lindsey S. Wiser | Summary: Claims of detections of gases in exoplanet atmospheres often rely on comparisons between models including and excluding specific chemical species. However, the space of molecular combinations available for model construction is vast […]

“Oh FUors where art thou”: A search for long-lasting YSO outbursts hiding in infrared surveys

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Carlos Contreras Peña, Jeong-Eun Lee, Ho-Gyu Lee, Gregory Herczeg, Doug Johnstone | Summary: Long-lasting episodes of high accretion can strongly impact stellar and planetary formation. However, the universality of these events during the formation of young stellar objects (YSOs) is still under debate. Accurate statistics of strong […]
