Photochemistry on Pluto: part II HCN and nitrogen isotope fractionation [0.03%]
冥王星光化学研究（二）：HCN和氮同位素分馏

We have converted our Titan one-dimensional photochemical model to simulate the photo- chemistry of Pluto's atmosphere and include condensation and aerosol trapping in the model. We find that condensation and aerosol trapping are important ...
Detecting galaxy-filament alignments in the Sloan Digital Sky Survey III [0.03%]
利用第三次斯隆数字天空调查发现银河系-丝状物的排列现象
Yen-Chi Chen,Shirley Ho,Jonathan Blazek et al.
Yen-Chi Chen et al.
Previous studies have shown the filamentary structures in the cosmic web influence the alignments of nearby galaxies. We study this effect in the LOWZ sample of the Sloan Digital Sky Survey using the 'Cosmic Web Reconstruction' filament cat...
Gas kinematics in FIRE simulated galaxies compared to spatially unresolved HI observations [0.03%]
FIRE模拟星系中的气体动力学与空间不可解析的HI观测数据比较
Kareem El-Badry,Jeremy Bradford,Eliot Quataert et al.
Kareem El-Badry et al.
The shape of a galaxy's spatially unresolved, globally integrated 21-cm emission line depends on its internal gas kinematics: galaxies with rotationally supported gas discs produce double-horned profiles with steep wings, while galaxies wit...

Alejandro González-Samaniego et al.
We use a suite of high-resolution cosmological dwarf galaxy simulations to test the accuracy of commonly used mass estimators from Walker et al. (2009) and Wolf et al. (2010), both of which depend on the observed line-of-sight velocity disp...
slug IV: a novel forward-modelling method to derive the demographics of star clusters [0.03%]
slug IV：一种新的正向建模方法，用于推导星团的人口统计学特征
Mark R Krumholz,Angela Adamo,Michele Fumagalli et al.
Mark R Krumholz et al.
We describe a novel method for determining the demographics of a population of star clusters, for example distributions of cluster mass and age, from unresolved photometry. This method has a number of desirable properties: it fully exploits...
The origin of the diverse morphologies and kinematics of Milky Way-mass galaxies in the FIRE-2 simulations [0.03%]
FIRE-2模拟中类似银河系天体形态和运动学的起源
Shea Garrison-Kimmel,Philip F Hopkins,Andrew Wetzel et al.
Shea Garrison-Kimmel et al.
We use hydrodynamic cosmological zoom-in simulations from the Feedback in Realistic Environments project to explore the morphologies and kinematics of 15 Milky Way (MW)-mass galaxies. Our sample ranges from compact, bulge-dominated systems ...

Sean P Fillingham et al.
In the local Universe, there is a strong division in the star-forming properties of low-mass galaxies, with star formation largely ubiquitous amongst the field population while satellite systems are predominantly quenched. This dichotomy im...
ETHOS - an effective theory of structure formation: predictions for the high-redshift Universe - abundance of galaxies and reionization [0.03%]
结构形成的有效理论ETHOS对高红移宇宙的预测：恒星系的数量以及再离子化过程
Mark R Lovell,Jesús Zavala,Mark Vogelsberger et al.
Mark R Lovell et al.
We contrast predictions for the high-redshift galaxy population and reionization history between cold dark matter (CDM) and an alternative self-interacting dark matter model based on the recently developed ETHOS framework that alleviates th...
Globular clusters in high-redshift dwarf galaxies: a case study from the Local Group [0.03%]
类星体周围恒星形成的触发机制及恒星形成效率上限研究——来自本地宇宙矮星系的案例分析

Tom O Zick
We present the reconstructed evolution of rest-frame ultraviolet (UV) luminosities of the most massive Milky Way dwarf spheroidal satellite galaxy, Fornax, and its five globular clusters (GCs) across redshift, based on analysis of the stell...
SIDM on FIRE: hydrodynamical self-interacting dark matter simulations of low-mass dwarf galaxies [0.03%]
SIDM在FIRE矮星系模拟中的效应
Victor H Robles,James S Bullock,Oliver D Elbert et al.
Victor H Robles et al.
We compare a suite of four simulated dwarf galaxies formed in 1010 M☉ haloes of collisionless cold dark matter (CDM) with galaxies simulated in the same haloes with an identical galaxy formation model but a non-zero cross-section for DM se...
