Lattice models and super telescoping formula [PDF]

open access: yesarXiv, 2021
In this paper, we introduce the super telescoping formula, a natural generalization of well-known telescoping formula. We explore various aspects of the formula including its origin and the telescoping cancellations emerging from symmetric patterns. We also show that the super telescoping formula leads to the construction of exactly solvable lattice ...

Seeing-limited imaging sky surveys -- small vs. large telescopes [PDF]

open access: yes, 2020
(Abridged) Typically large telescope construction and operation costs scale up faster than their collecting area. This slows scientific progress, making it expensive and complicated to increase telescope size. A metric that represents the capability of an imaging survey telescopes, and that captures a wide range of science objectives, is the telescope ...

To Telescope or Not To Telescope?

open access: yesRobotic Telescopes, Student Research and Education Proceedings, Vol 1, No 1, 2018
With the rapidly growing number of Internet-accessible and Internet-controlled research-grade telescopes becoming available, astronomy educators are rushing to create authentic research-programs for students that leverage these new resources. To date, the most successful programs are those that focus on upper-level science-focused students or highly ...

Neutrino Telescopes [PDF]

open access: yesAIP Conference Proceedings, 2006
The observation of high energy cosmic neutrinos can shed light on the astrophysical sites and mechanisms involved in the acceleration of protons and nuclei to the high energies observed at Earth by cosmic ray detectors. More generally, high energy neutrinos can be a key instrument in the multimessenger study of the high energy sky.

Active optics in astronomy – modeling of deformable substrates: freeform surfaces for FIREBall and MESSIER

open access: yesJournal of the Mechanical Behavior of Materials, 2018
Active optics techniques on large telescopes and astronomical instrumentations provide high imaging quality. For ground-based astronomy, the co-addition of adaptive optics again increases angular resolution up to providing diffraction-limited imaging at ...

Discrete Time Dynamic Model for Telescope Auto-Guiding System [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2007
In the auto-guiding system for obtaining a long exposure astrophotography, CCD camera is usually used for measuring guide errors which are affected by optical dispersion and mechanical disturbances.

Science with the Cherenkov Telescope Array [PDF]

open access: yes, 2017
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA is extremely broad: from understanding the role of relativistic cosmic ...

On the lithium abundance of the visual binary components ξ Boo A (G8V) and ξ Boo B (K5V)

open access: yesAstronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022
Abstract A spectroscopic investigation of the lithium resonance doublet in ξ Boo A and ξ Boo B in terms of both abundance and isotopic ratio is presented. We obtained new R = 130,000 spectra with a signal‐to‐noise ratio (S/N) per pixel of up to 3200 using the 11.8 m LBT and PEPSI.
