Fundamental Noise Limits of Infrared Detectors in the Presence of Readout Glow
Michael Bottom, Gustav Pettersson, Pavaman Bilgi +5
Read noise in infrared sensor arrays remains a major obstacle for ground- and space-based astronomy. It has long been recognized that the upcoming extremely large telescopes cannot…
SuperFIRE: Concept evolution of a seeing-limited broadband spectrograph for the GMT
Gustav M. Pettersson, Gábor Fűrész, Nathan P. Lourie +4
We are developing the SuperFIRE concept, which builds on the heritage of the FIRE spectrograph at Magellan, as a broadband (about 340 nm to 2.5 um) intermediate resolution (R=10,00…
A Multi-Wavelength View of the First Type Ic-BL Supernova with an Einstein Probe X-ray Shock Breakout
Jillian C. Rastinejad, Gokul Srinivasaragavan, Nikhil Sarin +36
The paper reports multi-wavelength observations of the nearby fast X‑ray transient EP260321a, identified as the shock‑breakout of a broad‑line Type Ic supernova (SN2026gzf), and us…
Optimal mitigation of random telegraph noise for improved photometry at high frame rates
Christopher Layden, Daniel-Rolf Harbeck, Tejus Deo-Dixit +3
Random telegraph noise (RTN) is a major contributor to read noise in many CMOS image sensors considered for astronomical use. While scientific CMOS image sensors deliver lower read…
The WINTER Observatory: A One-Degree InGaAs Survey Camera to study the Transient Infrared Sky
Danielle Frostig, Nathan Lourie, Viraj Karambelkar +20
The Wide-field Infrared Transient Explorer (WINTER) is a near-infrared time-domain survey instrument operating on a dedicated 1-meter robotic telescope at Palomar Observatory. The…
Multi-color characterization of optically invisible FU Orionis-type outbursts: Demonstration and prospects for the WINTER survey
Danielle Frostig, Kishalay De, Lynne A. Hillenbrand +8
Episodic mass accretion is the dominant mechanism for mass assembly in the proto-stellar phase. Although prior optical time-domain searches have allowed detailed studies of individ…
