P70-012: Deducing physical parameters of TDEs through spectroscopic lag studies

P.I.: Panos Charalampopoulos

This is a SoftToO program using ALFOSC (Classification 4h total, follow-up of 2 TDEs, 6h each ) in Nordic Service or technical nights.

Requested setup:

  • Grism #4
  • Slit_1.0, Slit_1.3

Observing instructions:

When an observation is triggered, OBs will be made and submitted to the Queue:
  • In a sequencer window type cd ~/scripts/70-012/
  • Look for the most recent scripts with ls -lrt and execute them
  • Remember to update the OBs and send the SoftToO report

70-012 2024-10-18 00:51 SoftToO AT2024wsd, Feige34 ALHj180196 - ALHj180200 ; ALHj180207 - ALHj180211 Target observed with clear skies and seeing around 1.3-2 arcsec. Observed
70-012 2024-10-26 00:02 SoftToO BD174708 ALHj260162 - ALHj260166 Bad weather prevented further observations, only a standard was observed which was shared from another proposal Failed
70-012 2024-10-27 00:00 SoftToO No observations could be taken due to bad weather. Failed
70-012 2024-10-30 01:12 SoftToO AT2024led, AT2024zkr ALHj300062 - ALHj300067, ALHj300105 - ALHj300109 Both targets showed clear spectral features in Quickspec. The rest of the targets were missed as there were many SoftToOs to observe from other programs as well. The standard star files ALHj300071 & ALHj300072, observed as part of another proposal, can be used for calibration because the setup is the same (Grism 4 and 1.0'' slit). Observed
