The epoch of cosmic dawn, occurring in the first few hundred million years after the Big Bang, marks a critical period in the formation of the first galaxies and the reionization of the Universe. With the unprecedented capabilities of the James Webb Space Telescope (JWST), deep imaging surveys such as COSMOS-Web have opened a new window into this early era.
In this study, we employ the...
The measurement of galaxy-galaxy strong lens number density provides statistical constraints on foreground mass distributions. Dusty star-forming galaxies (DSFGs) uncovered in submillimeter surveys are particularly valuable for this purpose, given the large cosmological volumes they probe. Strongly lensed DSFGs have predominantly been identified as one of the brightest sources in previous...
Observations of the stellar medium have revealed many structures forming prior to the birth of stars. Filaments being omnipresent and highly correlated with prestellar cores, stellar cluster that contain massive stars are usually found to be embedded in a hub-filament system. Continuum observations could not reveal 3D information, while spectroscopic observations have suggested that...
The change in the relative importance of gravity, turbulence, and magnetic field affects the fragmentation of massive star-forming dark clouds. Using dust continuum and polarization data, as well as molecular transition lines from the JCMT, IRAM-30m and the SMA, we investigated the energetics of various star forming regions to understand the correlation between the three factors and...
Space weather events sourced from host stars, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence an exoplanet’s habitability and atmospheric evolution history. These time-dependent events may also affect our ability to measure and interpret its properties by modulating reservoirs of key chemical compounds and/or by changing the brightness...
The joint discovery of the binary neutron star (BNS) merger GW170817 and the associated short gamma-ray burst GRB170817A has shed new light on the study of such systems. In this work, assuming all BNS mergers produce GRBs, we aim to investigate the jet geometry of short gamma-ray bursts through a multimessenger approach. Our analysis incorporates observations from two BNS merger events,...
The production mechanism of fast radio bursts (FRBs) remains elusive, and potential correlations between burst occurrence times and various burst properties may offer important clues. Among them, the spectral peak frequency is particularly important because it may encode direct information about the physical conditions and environment at the emission site. Analyzing over 4,000 bursts from the...
