The Persistent Missing Mass Problem in Planet Formation

open access: yesThe Astrophysical Journal Letters
Recent ground-based microlensing surveys suggest that our Galaxy may abound with small free-floating planets, potentially up to ∼21 such planets per star. We explore the implication of such possibility on the mass budget for planet formation.

Spectral Appearance of Self-gravitating Disks Powered by Stellar Objects: Universal Effective Temperature in the Optical Continuum and Application to Little Red Dots

open access: yesThe Astrophysical Journal Letters
We revisit the spectral appearance of extended self-gravitating accretion disks surrounding compact central objects such as supermassive black holes. Using dust-poor opacities, we show that all optically thick disk solutions possess a universal outer ...

H i Observations of Giant Low Surface Brightness Galaxies

open access: yesThe Astrophysical Journal
Giant low surface brightness (gLSB) galaxies are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses, which can reach 10 ^12 M _⊙ .

Occurrence Rates of Accreting Companions from a New Method for Computing Emission-line Survey Sensitivity: Application to the Hα Giant Accreting Protoplanet Survey

open access: yesThe Astronomical Journal
A key scientific goal of exoplanet surveys is to characterize the underlying population of planets in the local galaxy. In particular, the properties of accreting proto planets can inform the rates and physical processes of planet formation. We develop a

McFACTS III: Compact Binary Mergers from Active Galactic Nucleus Disks over an Entire Synthetic Universe

open access: yesThe Astrophysical Journal
The active galactic nucleus (AGN) channel for the formation of binary black hole (BBH) mergers has been previously studied as a potential formation channel for the merging compact binaries observed by the LIGO–Virgo–KAGRA (LVK) scientific collaboration ...

Neutrino Emission from Gamma-Ray Burst Jet Inside the Cavity within Active Galactic Nucleus Accretion Disks

open access: yesThe Astrophysical Journal
Active galactic nucleus (AGN) accretion disks are promising sites for compact binary mergers. Short gamma-ray burst (SGRB) jets from binary neutron star coalescence can propagate within low-density cavities carved by circumbinary outflows. We investigate

Anisotropy of Core-collapse Supernovae Effected by the Disks of Active Galactic Nuclei

open access: yesThe Astrophysical Journal
Active galactic nuclei (AGN) disks provide dense environments that influence star formation, evolution, and migration. In AGN disks, pressure gradients and migration accelerations could create the anisotropy of the core-collapse supernovae that occurs ...
