Microlensing of Lensed Supernovae
Given the number of recently discovered galaxy-galaxy lens systems, we anticipate that a gravitationally lensed supernova will be observed within the next few years. We explore the possibility that stars in the lens galaxy will produce observable microlensing fluctuations in lensed supernova light curves. For typical parameters, we predict that ∼70% of lensed SNe will show microlensing fluctuat...
متن کاملDetecting Z > 2 Type Iin Supernovae
Type IIn supernovae (SNe IIn) dominate the brightest supernova events in observed FUV flux (∼1200 − 2000Å). We show that multi-band, multi-epoch optical surveys complete to mr = 27 can detect the FUV emission of ∼25 z > 2 SNe IIn deg yr rest-frame (∼10 SNe IIn deg yr observed-frame) to 4σ using a technique monitoring color-selected galaxies. Moreover, the strength and evolution of the bright em...
متن کاملTHE SDSS DISCOVERY OF A STRONGLY LENSED POST-STARBURST GALAXY AT z=0.766
We present the first result of a survey for strong galaxy-galaxy lenses in Sloan Digital Sky Survey (SDSS) images. SDSS J082728.70+223256.4 was selected as a lensing candidate using selection criteria based on the color and positions of objects in the SDSS photometric catalog. Follow-up imaging and spectroscopy showed this object to be a lensing system. The lensing galaxy is an elliptical at z ...
متن کاملDISCOVERY OF A VERY BRIGHT STRONGLY LENSED GALAXY CANDIDATE AT z ≈
Using Hubble Space Telescope (HST) and Spitzer IRAC imaging, we report the discovery of a very bright strongly lensed Lyman break galaxy (LBG) candidate at z ∼ 7.6 in the field of the massive galaxy cluster Abell 1689 (z = 0.18). The galaxy candidate, which we refer to as A1689-zD1, shows a strong z850 − J110 break of at least 2.2 mag and is completely undetected (< 1 σ) in HST Advanced Camera ...
متن کاملDISCOVERY OF A VERY BRIGHT STRONGLY - LENSED GALAXY CANDIDATE AT z ≈ 7
Using Hubble Space Telescope (HST ) and Spitzer IRAC imaging, we report the discovery of a very bright strongly-lensed Lyman break galaxy (LBG) candidate at z ∼ 7.6 in the field of the massive galaxy cluster Abell 1689 (z = 0.18). The galaxy candidate, which we refer to as A1689-zD1, shows a strong z850 − J110 break of at least 2.2 magnitudes. The source is completely undetected (< 1σ) in HST A...
