The Large-scale Structure Supplies the Formation of Gas-star Misaligned Galaxies

open access: yesThe Astrophysical Journal Letters
Using the integral field unit data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we build a sample of gas-star misaligned galaxies. The large-scale environment of misaligned galaxies is dominated by filaments and clusters, while it

Spatially Resolved Kinematics of Post-starburst Galaxies

open access: yesThe Astrophysical Journal
Star-forming galaxies can reach quiescence via rapid transition through merger-triggered starbursts that consequently affect both their kinematics and star formation rates.

Dwarf and Intermediate-mass Galaxies in MaNGA: Evidence for Different Evolutionary Trends

open access: yesThe Astrophysical Journal
We investigate the interplay between morphology, specific star formation rate (sSFR), and local environment using a sample of 7408 galaxies from the fourth-generation Sloan Digital Sky Survey Mapping Nearby Galaxies at Apache Point Observatory survey ...

Dusty-wind-clear JWST Super-early Galaxies

open access: yesThe Astrophysical Journal Letters, 2023
The JWST discovery of a number of super-early (redshift z > 10) blue galaxies requires these systems to be essentially dust free in spite of their large stellar masses. A possible explanation is that dust is evacuated by radiatively driven outflows.

The Delay Time Distribution of Tidal Disruption Events

open access: yesThe Astrophysical Journal
Tidal disruption events (TDEs) can be observed when stars get too close to supermassive black holes and are torn apart and accreted. The delay time distribution of TDEs, or rate of TDEs as a function of time since a burst of star formation, can be used ...

Diverse reddening distributions in sight lines for type Ia supernovae

open access: yesAstronomy & Astrophysics
Context. Accurate cosmological constraints from type Ia supernovae (SNe) require sufficiently accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the problem of disentangling the SN’s intrinsic colours from host ...

H i Gas and Star Formation in Major Galaxy Pairs from the FAST All Sky H i Survey (FASHI)

open access: yesThe Astrophysical Journal
Atomic hydrogen (H i ) plays a fundamental role in fueling star formation in galaxies. However, the behavior of H i gas in interacting systems, particularly galaxy pairs, remains elusive.
