Type II supernovae (SNe II) are excellent tools for studying stellar evolution, mass loss, cosmology, and to probe possible explosion mechanisms. By examining the spectroscopic diversity of SNe II, this thesis aims to improve the...
The identities of the progenitors of type Ia supernova (SN Ia) has long been under study and remains an unsolved problem of astrophysics. The answer to this question will impact cosmology and subfields such as galactic evolution. To help...
Type Ia supernovae (SNe Ia) are rather homogeneous astrophysical objects and can be used as cosmological distance ladders. Despite that, significant diversity among SNe Ia luminosity (by a factor of ~ 10) and spectral properties have...
Observations indicate that massive stars ends their lives violently, but exactly how massive they need to be remains an astrophysical challenge. Stellar evolution predicts make two fundamental predictions about the fate of massive stars....
Type Ia supernovae (SNe Ia) mark the beginning and the end of stellar evolution. They are one of the most powerful cosmological probes in our universe thanks to their high intrinsic luminosities and standardizable properties. In the...
We performed forecasts of the uncertainty with which future surveys will measure the cosmological parameters of the non-flat ΛCDM model, extended to include the sum of neutrino masses Σν, and the effective number of relativistic species...
Using three magnified Type Ia supernovae (SNe Ia) detected behind CLASH (Cluster Lensing and Supernovae with Hubble) clusters, we perform a first pilot study to see whether standardizable candles can be used to calibrate cluster mass...
Massive stars play a crucial role in the universe. Yet, our understanding of massive stars remains incomplete due to their rarity, short lifetimes, complexity of binary interactions, and imprecise Galactic distances. An important...

Despite the triumph of Type Ia Supernovae measuring cosmological distances, many of the details of the origin and evolution of SNe Ia remain unknown or highly controversial. There is still much debate about the specifics of the earliest...

An ionized Very-High Velocity Cloud (VHVC, vLSR ∼ −350 km s−1 was recently discovered in multiple ion absorption lines (e.g., O i, C ii, Si ii, Si iii) in the sightline of M33 (Zheng et al. 2017). However, the VHVC’s origin is still...
