本报告基于多波段观测，系统地阐述了星际尘埃在星系演化中的关键作用及其与恒星形成的双向互动关系。主要研究发现包括：局部尺度：MWST对鹰状星云的高分辨率观测揭示了辐射反馈触发恒星形成的证据，并发现极端环境下的尘埃消光定律偏离标准模型。银河系尺度：发现超新星驱动的巨型超级气泡可长期维持并抗衡星系剪切；超新星遗迹的观测直接证明激波会增大尘埃颗粒平均尺寸。星系尺度：在 M31 外盘发现大质量恒星，挑战了恒星形成仅发生于高尘埃密度区域的传统认知。该报告成果用于揭示星际尘埃与恒星通过形成与反馈机制相互塑造，驱动着星系的动态演化。

For decades, physicists and astronomers have grappled with a fundamental cosmic mystery: the origin of cosmic rays, particularly around the so-called knee of the energy spectrum at E ≳ 1 PeV (10¹⁵eV). While the Galactic origin of this spectral feature - identified as early as the 1950s - is widely accepted, pinpointing the astrophysical objects capable of accelerating particles to such extreme energies has remained a significant challenge. In recent years, however, a compelling set of clues has begun to emerge. Dozens of extraordinary objects have now been discovered across the Milky Way emitting ultra-high-energy (E ≳0.1 PeV) gamma rays, revealing the locations of extreme cosmic-ray factories known as PeVatrons. These sources span a remarkably diverse range of environments and physical processes, including supernova remnants, young star-forming regions, rapidly rotating neutron stars, and compact binaries powered by accreting black holes. Remarkably, despite this diversity, all of these systems appear to share a common potential: they function as extreme particle accelerators, operating close to fundamental theoretical limits. Although the search for Galactic PeVatrons has only just begun, these discoveries suggest that we may finally be approaching a long-sought understanding of the most potent engines of relativistic plasma in our Galaxy and of how they supply high-energy cosmic rays to the Milky Way.

Millisecond pulsars (MSPs) sit at the crossroads of extreme magnetospheric physics and a long-standing Galactic Center mystery: the GeV Excess (GCE), for which MSPs remain the leading astrophysical explanation. In this talk, I present a multi-messenger investigation that links gamma-ray phenomenology to gravitational-wave prospects. First, using 15 years of Fermi-LAT observations, we uncover a robust phase-resolved correlation between gamma-ray luminosity and spectral cutoff energy in our MSP sample. This trend provides new evidence favoring particle acceleration and curvature radiation associated with the Equatorial Current Sheet, and it highlights tensions with standard Outer Gap interpretations. Second, we turn to the GCE debate. If the excess is powered by thousands of unresolved bulge MSPs, can we hear them through continuous gravitational waves? We systematically model the expected continuous-wave emission from such a population under representative deformation scenarios and realistic search considerations. While the predicted signals are below the reach of current detectors, next-generation interferometers, such as the Einstein Telescope and Cosmic Explorer, could probe a detectable fraction of the population, offering an independent multi-messenger test of the MSP origin of the Galactic Center Excess.
