COSMOS-Web: Unraveling the Evolution of Galaxy Size and Related Properties at $2<z<10$

Posted by dbos April 9, 2025April 14, 2025This Week: Astrophysics, Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Lilan Yang, Jeyhan S. Kartaltepe, Maximilien Franco, Xuheng Ding, Mark J. Achenbach | Summary: We measure galaxy sizes from $2 < z < 10$ using COSMOS-Web, the largest-area JWST imaging survey to date, covering $sim$0.54 deg$^2$. We analyze the rest-frame optical (~5000A) size evolution and its […]

Discovery of extreme Quasi-Periodic Eruptions in a newly accreting massive black hole

Posted by dbos April 9, 2025April 14, 2025MIT, This Week: Astrophysics

Kavli Affiliate: Erin Kara | First 5 Authors: Lorena Hernández-García, Joheen Chakraborty, Paula Sánchez-Sáez, Claudio Ricci, Jorge Cuadra | Summary: Quasi-periodic eruptions (QPEs) are rapid, recurring X-ray bursts from supermassive black holes, believed to result from interactions between accretion disks and surrounding matter. The galaxy SDSS1335+0728, previously stable for two decades, exhibited an increase in […]

Rapidly varying ionization features in a Quasi-periodic Eruption: a homologous expansion model for the spectroscopic evolution

Posted by dbos April 9, 2025April 14, 2025MIT, This Week: Astrophysics

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Peter Kosec, Erin Kara, Giovanni Miniutti, Riccardo Arcodia | Summary: Quasi-Periodic Eruptions (QPEs) are recurring bursts of soft X-ray emission from supermassive black holes (SMBHs), which a growing class of models explains via extreme mass-ratio inspirals (EMRIs). QPEs exhibit blackbody-like emission with significant temperature evolution, […]
