This consolidated grant proposal brings together research within the Jeremiah Horrocks Institute (JHI) of the University of Central Lancashire (UCLan) in the key research areas of stellar astrophysics, Galactic astrophysics, and extra-Galactic astrophysics. In these areas we will be addressing key science questions at the cutting edge of astrophysical research. Some examples of these are given here.In the area of stellar astrophysics, we will solve some of the currently unanswered key questions in star formation, particularly those surrounding the formation, structure and evolution of prestellar cores, and the role played by magnetic fields in particular in this process. This is important, because there is believed to be a link between the core mass function and the stellar Initial Mass Function (IMF). It is planned that this will lead us to a true physical understanding of the origin of the IMF itself. We will also study the evolution of discs around protostars and the effects of binarity on planet formation, and model the migration of giant planets in discs around protostars to see how this is affected by stellar luminosity and the properties of the disc. In addition, we will also attempt to explore and understand internal angular momentum transport in hydrogen-burning, main-sequence stars, and we will search for the progenitors of supernovae.In the areas of Galactic and extra-Galactic astrophysics (including the Milky Way as the nearest galaxy) we will investigate how the energy balance in the ISM, the conversion of gas into stars, and the IMF of the stellar progeny are affected by the dramatically changing physical conditions on galaxy-wide scales. We will probe the distribution of molecular gas and dust with high spatial resolution, to understand the origin of these components in dusty early-type galaxies. We will dissect the evolution of the Milky Way bulge, bar and disc, and compute orbits, in a suite of N-body+SPH simulations in order to help interpret Gaia data. Thereby we will better understand the role of the bar in the overall evolution of the Milky Way, as well as its mass assembly. For powerful Active Galactic Nuclei (AGN) we will develop re-collimation shock simulations in jets to include additional physics and realistic conditions, in order to better understand these highly energetic phenomena

这项综合拨款提案汇集了中央兰开夏大学（UCLan）耶利米霍罗克斯研究所（JHI）在恒星天体物理学，银河天体物理学和银河系外天体物理学的关键研究领域的研究。在这些领域中，我们将在天体物理学研究的前沿解决关键的科学问题。在恒星天体物理学领域，我们将解决星星形成过程中一些尚未解决的关键问题，特别是星前核的形成、结构和演化，以及磁场在这一过程中所起的作用。这一点很重要，因为人们相信核心质量函数和恒星初始质量函数（IMF）之间存在联系。这将使我们对国际货币基金组织本身的起源有一个真正的物理理解。我们还将研究原恒星周围圆盘的演化和双星对行星形成的影响，并模拟原恒星周围圆盘中巨行星的迁移，以了解这是如何受到恒星光度和圆盘性质的影响。此外，我们还将尝试探索和理解燃烧氢的主序星的内部角动量输运，并将寻找超新星的祖先。在银河系和银河系外天体物理学领域（包括银河系作为最近的星系），我们将研究如何在ISM的能量平衡，气体转化为恒星，和恒星后代的IMF受到星系尺度上剧烈变化的物理条件的影响。我们将以高空间分辨率探测分子气体和尘埃的分布，以了解这些成分在尘埃早型星系中的起源。我们将在一套N体+SPH模拟中剖析银河系凸起、棒和盘的演化，并计算轨道，以帮助解释盖亚数据。因此，我们将更好地了解酒吧在银河系的整体演化中的作用，以及它的质量组装。对于强大的活动星系核（AGN），我们将开发喷流中的重新准直冲击模拟，以包括额外的物理和现实条件，以便更好地理解这些高能现象
