SpecCLIP: Aligning and Translating Spectroscopic Measurements for Stars

The Astrophysical Journal
In recent years, large language models (LLMs) have transformed natural language understanding through vast data sets and large-scale parameterization. Inspired by this success, we present SpecCLIP, a foundation model framework that extends LLM-inspired ...

Comparing the Host Galaxies of Type Ia, Type II and Type Ibc Supernovae

, 2014
We compare the host galaxies of 902 supernovae, including SNe Ia, SNe II and SNe Ibc, which are selected by cross-matching the Asiago Supernova Catalog with the SDSS Data Release 7.

A New Wide-field Infrared Survey Explorer Calibration of Stellar Mass

The Astrophysical Journal, 2023
We derive new empirical scaling relations between Wide-field Infrared Survey Explorer (WISE) mid-IR (MIR) galaxy photometry and well-determined stellar masses from spectral energy distribution modeling of a suite of optical–infrared photometry provided ...

Spectral Properties of Galaxies in Void Regions

, 2015
We present a study of spectral properties of galaxies in underdense large-scale structures, voids. Our void galaxy sample (75,939 galaxies) is selected from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) with $\rm z < 0.107$. We find that there

CORMASS: A Compact and Efficient NIR Spectrograph for Studying Low-Mass Objects [PDF]

, 2000
CorMASS (Cornell Massachusetts Slit Spectrograph) is a compact, low-resolution (R=300), double-pass prism cross-dispersed near-infrared (NIR) spectrograph in operation on the Palomar Observatory 60-inch telescope.

Near-infrared spectra of ISO selected Chamaeleon I young stellar objects

, 2002
We present 0.95--2.5 micron moderate (R = 500) resolution spectra of 19 ISOCAM detected sources in the Chamaeleon I dark cloud. Thirteen of these stars are candidate very low mass members of the cloud proposed by Persi et al.
