چکیده

This paper presents some speculations about alternatives to the recently disproved telescope conjecture in stable homotopy theory. It includes a brief introduction to the parametrized Adams spectral sequence, the main technical tool used to disprove it. An example supporting the new conjectures is described.

Pulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I

We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

داده‌کاهی و آنالیز تصاویر چند باندی نوری بلازار 180 Mrk

 Nearly simultaneous multiband monitoring of blazars is very limited and most studies reported in literature are conflicting, too. Although optical variability on intra-night timescales is now a well established phenomenon for blazars, its relationship to long-term variability remains unclear. Possible clues could come from monitoring the optical spectrum for correlation with brightness. The pr...

Simulations of (MC)AO for a 100m telescope

In this paper, we summarize the analysis made on various Adaptive Optics (AO) modes (including ShackHartmann (SH) and Pyramid Wavefront Sensors (PWS)) for the OverWhelmingly Large telescope (OWL). We will show some early results of the performance to be expected with a first generation AO system, working in the infrared. Several telescope diameters were considered to see the variations as a fun...

مشاهده سایه خورشید با تلسکوپ ردیاب پرتوهای کیهانی

A cosmic ray tracking telescope has been made for the measurement of cosmic rays from different directions, especially those received from the sun direction. Our observations by the telescope shows a noticeable deficiency in the detected number of cosmic rays entering the telescope when its axis was pointing to the sun compared to that entering the telescope with no sun in its field of view. Th...
