On the connection between nitrogen-enhanced field stars and the Galactic globular clusters

Posted by klaurent Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Sarah G. Kane, Sarah G. Kane, , , | Summary: As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the Milky Way, our best tracers of the […]

Multi-color characterization of optically invisible FU Orionis-type outbursts: Demonstration and prospects for the WINTER survey

Posted by klaurent MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Danielle Frostig, Danielle Frostig, , , | Summary: Episodic mass accretion is the dominant mechanism for mass assembly in the proto-stellar phase. Although prior optical time-domain searches have allowed detailed studies of individual outbursts, these searches remain insensitive to the earliest stages of star formation. In […]

A carbon-rich atmosphere on a windy pulsar planet

Posted by klaurent Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Michael Zhang, Michael Zhang, , , | Summary: A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum density of 1.8 g/cm^3 and its ~1900 K equilibrium temperature. We use […]

Disentangling Multiple Gas Kinematic Drivers in the Perseus Galaxy Cluster

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, XRISM Collaboration, , , | Summary: Galaxy clusters, the Universe’s largest halo structures, are filled with 10-100 million degree X-ray-emitting gas. Their evolution is shaped by energetic processes such as feedback from supermassive black holes (SMBHs) and mergers with other cosmic structures. The imprints of […]

PromptEnhancer: A Simple Approach to Enhance Text-to-Image Models via Chain-of-Thought Prompt Rewriting

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Linqing Wang, Linqing Wang, , , | Summary: Recent advancements in text-to-image (T2I) diffusion models have demonstrated remarkable capabilities in generating high-fidelity images. However, these models often struggle to faithfully render complex user prompts, particularly in aspects like attribute binding, negation, and compositional relationships. This leads […]
